Testing Done: clag bond add/del and clag slave add/del
This change basically does the following -
1. Proto-down swpX pre-clag-bond-enslave
2. Proto-up swpX post-clag-bond-release
Setting/clearing of clag-id will result in similar proto-state changes
and those are handled by clagd.
Note:
I really wanted to keep these changes out of ifupdown2 but the
order of setting is critical i.e. protodown has to happen enslave to
prevent additional flaps/STP TCNs. Theoretically #2 can be done by clagd
but there is no easy way to do #1.

- 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
