This branch resolves issue #462; Auto growing PVs. Specifically, it looks at the LVM PVs on the host and checks to see if there is unused free space after the backing partition. If there is, it auto-grows the partition and then resizes the PV. This featu
re is designed to make life easier for users who deleted the auto-created '/home' partition during the anaconda disk partitioning tool.
* Created Storage->auto_grow_pv() that does the above.
* Added the missing hidden method name _create_rsync_wrapper in the Storage module POD.
* Added a call to Storage->auto_grow_pv() in anvil-configure-host and anvil-version-changes for nodes and DR.

* Updated Server->connect_to_libvirt() to check that the target URI's
SSH fingerprint is recorded before connecting. Also added an alarm
wrapper around the Sys::Virt->new() call.
* Continued work on anvil-manage-server-system, working on the boot
order section now.

* Updated Server->locate() to take the new 'anvil' parameter to speed up
searches.
* Updated Server->update_definition() to use Server->locate() to find
where updates are needed. It now also defines the server with the new
config.

* If the call to Remote-call() set the target that was actually the
local short hostname, it would fail to make the call at all. Now if
the 'target' is local, the shell call is instead passed to
System->call() instead.
* Cleaned up logging.

* Updated Get->host_name() to accept the new 'refresh' parameter. This
forces a reread of the hostname, instead of using the cached value.
* Updated System->host_name() so that, when it's updating the hostname,
it updates the database and cached variables.
* Updated Words->center_text() to avoid undefinied parameter issues.
* Updated anvil-join-anvil to ensure the 'sys::host_name' variable.

Moved the logic to a new private method, and call it now from the active
Striker in the once per minute loop. The duplicate variable issue seems
to be not entirely uncommon.

With this new system, a 'primary_db' is chosen (first connected DB UUID when sorted) and only it does resyncs. Further, resyncs have been pulled from all tools except anvil-daemon. So with this new system, the chances of duplicate, simultaneous resyncs should be removed (hopefully for real this time).
* Database->check_agent_data() no longer calls a resync after loading a
schema.
* Removed the Database->coonnect() 'all' parameter
* The database used to read from is now always the same as the primary,
even if there is a local DB.
* Database->connect() 'check_for_resync' parameter can now be set to
'2', which means "check for resync _if_ I am primary", where '1' still
checks for resync no matter what.

* Updated Database->get_jobs() to take 'job_host_uuid = all' to allow
loading jobs from all cluster machines. Also updated it to record the
'job_host_uuid' and the unix timestamp version of 'modified_date'.

Added DB connections to ocf:alteeve:server when starting or stopping
servers. This is to ensure that the servers -> server_state are updated
properly.

* Updated anvil-delete-server to use the new Server->locate method. This
was done as the old Server->locate() was failing to find the server
running on the peer when anvil-delete-server was running on the backup
subnode.
* Updated Server->locate() to search hosts for XML definition and DRBD
configs so that it can record where the server is recorded to run,
even if the server isn't running or defined at the time the locate ran.

* On subnodes and DR hosts, a check is made now in Storage->check_files() for files not linked in file_locations. Any found are added, with a check to see if the file already exists locally and, if so, that the md5sum is accurate or not (to set if the file is ready for use or not).

* Updated ocf:alteeve:server to test access over a given IP before calling Server->find to avoid timeouts when the peer is down. Also updated it to set the constraints to keep the server on the new host when the old host returns to the cluster.
* Fixed a bug in scan-cluster where a server that is FAILED but not running is now properly recovered.
Signed-off-by: digimer <mkelly@alteeve.ca>
* In DRBD->get_next_resource(), implemented a "hold" system where the DRBD minor and TCP port(s) returned are marked as being held for one minute. So subsequent calls won't use the same numbers.
* In anvil-daemon, added a check in run_jobs() where only one instance of a given job command will be started per 2-second loop. This should help reduce the chance of simultaneous race confitions in general.
* Removed from anvil-provision-server and most other tools the call to Job->get_job_uuid(). If the program is called without the job_uuid, don't try to find it. This allows a human (or script) to make repeated calls to a program without one of those calls running a pending job instead.

* Created Database->track_files() as a dedicated method as trying to verify the existence of file_locations during Database->load_anvils() was fragile and prone to recursive loops.
* Updated Database->insert_or_update_file_locations() to take an anvil_uuid and recursively call for each host, to maintain compatibility with the old ways, and make it simpler to add an entry for both sub-nodes in an Anvil!.
* Created Storage->push_file() that takes a file and rsync's it to all other machines, or creates a job for the file to be pulled if the target can't be accessed.
* Updated anvil-manage-files and anvil-sync-shared to use the new Storage->push_files and Database->track_files methods.
Signed-off-by: digimer <mkelly@alteeve.ca>
* To update file handling for the new DR host linking mechanism, file_locations -> file_location_anvil_uuid was changed to file_location_host_uuid.
This required a fair number of changes elsewhere to handle this, with a particular noted change to Database->get_anvils() to look at host_uuid's for the subnodes in an Anvil! and, if either is marked as needing a file, make sure the peer is as well. Similarly, any linked DRs are set to have the file as well.
* Created a new Network->find_access that simply takes a target host name or UUID, and it returns a list of networks and IPs that the target can be accessed by.
* Updated Network->load_ips() to find the network interface being used for traffic so that things like the interface speed can be recorded, even when an IP is on a bridge or bond.
Unrelated, but in this commit, is a restoration of calling scan agents with a timeout now that the virsh hang issue has been resolved.
