Migrate configuration files from 0.0.8 or earlier to 0.1.0 or later

Since 0.1.0, some paths have been changed as shown in the following table.

Type	0.0.8 or earlier	0.1.0 or later
Config Directory (User)	$HOME/.vbmc	$HOME/.vsbmc
Config Directory (System)	/etc/virtualbmc	/etc/vbmc4vsphere
Config File	virtualbmc.conf	vbmc4vsphere.conf
Environment Variable to point Config File	VIRTUALBMC_CONFIG	VBMC4VSPHERE_CONFIG

To migrate the old configuration files, simply rename the directory and file, then restart vsbmcd.

For most use cases, the migration will usually be completed with the following one line.

mv $HOME/.vbmc $HOME/.vsbmc
