scheduler: remove base.ini dependency for imaging api

Scheduler can be installed stand-alone where there is no
/etc/mmc/plugins/base.ini file

This base.ini was used to get ldap root password for some method
authentication.

So, I remove ldap authentication for these methods:

msc.get_web_def_coh_life_time
msc.get_web_def_attempts_per_day
imaging.synchroComputer
scheduler: Restore imaging bootmenu when stopping commands

When you click on audit page to stop commands, check if command is WOL
with imaging and restore bootmenus
