* Got the node/dr host initialization form to the point where it can test access and decide if it should show the Red Hat account form. Decided that for M3, node/dr host setup will now be a four-stage process; initial install (over PXE), initialization (install the proper anvil-{node,dr} RPM and connect to the database), setup/map the network, and then add to an Anvil! pair.
* Updated striker to no longer try to SSH to a remote machine. To enable this, we'd have to give apache a shell and an SSH key, which is dumb and dangerous when considered.
* Created tools/striker-get-peer-data which is meant to be invoked as the 'admin' user (via a setuid c-wrapper). It collects basic data about a target machine and reports what it finds on STDOUT. It gets the password for the target via the database.
* Updated anvil-daemon to check/create/update setuid c-wrapper(s), which for now is limited to call_striker-initialize-host.
* Created Anvil/Tools/Striker.pm to store Striker web-specific methods, including get_peer_data() which calls tools/striker-initialize-host via the setuid admin call_striker-initialize-host c-wrapper.
* In order to allow striker via apache to read a peer's anvil.version, which it can no longer do over SSH, any connection to a peer where the anvil.version is read is cached as /etc/anvil/anvil.<peer>.version. When Get->anvil_version is called as 'apache', this file is read instead.
* Updated Database->resync_databases() and ->_find_behind_databases() to ignore the 'states' table.
* Created tools/striker-initialize-host which will be called as a job to initialize a node/dr host.
