esxi-patch-start

Set the ESXi software VIB install acceptanceLevel

Set maintenanceMode on an ESXi system. In addition to setting it on the system, also record the state on DRP in the Param esxi/maintenance-mode.

Subsequently, when maintenance mode is disabled, BOTH the system state must be in maintenance (Enabled), and the DRP Param set to Enabled. This is a safety check to insure that DRP set the maintenance mode, and to not disable it unless we've set it.

Uses the esxi-params.py.tmpl python code to set/manage Params on the system.
