Ticket: CM-3346
Reviewed By:
Testing Done: Tested ifupdown2 sanity
- moved 'admin up' delays that we introduced recently to be
configurable via two ifupdown2.conf attributes
# Let link master (bridges, bonds) own the link state of slaves
link_master_slave=1
# Delay admin state change till the end
delay_admin_state_change=0
- reduced some redundant traversal of dependency trees
- fixed a few bugs in query check
