* Updated Database->get_hosts() to store hosts in a host_type hash.
* Updated Database->get_servers() to store servers by name, regardless
of host Anvil! node.

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 striker-update-cluster to take '--timeout' and a number of seconds, or 'Xm' or 'Xh' for minutes or hourse, respectively. Also updated to show the remaining time while waiting, and added waiting timeout to the rest of the while loops that prior had no time limit. This addresses issue #383 and issue #382.

* Updated DRBD->manage_resource() to set allow-two-primaries=no when up'ing a resource (as no migration can be in progress during an up command).

* 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.
