Add node autoflush service and target Add a systemd service to manage node flush/unflush, useful during system startup and shutdown to avoid requiring administrator intervention for this to occur. This is optional and the service is not enabled by default, and the postinst script informs the administrator of this. Also adds a systemd target to collect the two service units together and provide an easy way to flush+shutdown or startup+unflush the entire PVC system. Closes #28

# Parallel Virtual Cluster autoflush daemon
[Unit]
Description = Parallel Virtual Cluster autoflush daemon
Set flush after pvcapid.service This may or may not help, but should in theory prevent the flush from trying to run after a (locally-running) API daemon is terminated, which could cause an API failure and a failure to flush.

After = pvcnoded.service pvcapid.service
Don't use Requires as the dep is too hard Requires seems to flush on every service restart which is NOT what we want. Use Wants instead.

Wants = pvcnoded.service
Use consistent naming of components Rename "pvcd" to "pvcnoded", and "pvc-api" to "pvcapid" so names for the daemons are fully consistent. Update the names of the configuration files as well to match this new formatting. References #79

Perform additional tweaks to units Use RemainAfterExit to avoid pvc-flush from auto-stopping immediately. Use PartOf to tie services to the target itself. Use --wait on flush to avoid daemon stopping before flush is complete.

Add significant TimeoutSec to pvc-flush service This will stop systemd from killing the service in the middle of a flush or unflush operation, which completely defeats the purpose. 30 minutes was chosen as this is a very large but still somewhat manageable value, which should cover even a very large very loaded cluster with room to spare.
