a logical interface comes up

Testing Done: Tested ifup, ifdown in bond bridge setup
Also, implicitly pick up the upperifaces (even when user has not
specified --with-depends) for logical interfaces.
This is because when a logical interface goes down/deleted, kernel
impilicity deletes its upperifaces. so its better to implicitly bring
up upperifaces.

Testing Done: Tested ifup/ifdown
Before this patch, `ifup --with-depends <iface>` only brought up
lowerdevices. Because those were enough for iface to function.
And if ifaces above it (upperdevices) needed fixing, user could just
execute `ifup --with-depends <ifaceupper>`.
But in a recent, bond under a bridge bug in 2.0, got me thinking that
its probably better to up the upperdevices which might be impacted as
well. and this patch does just that.
The patch includes changes to make ifupdown generate dependency
information for all interfaces even if the user requested to operate
on a single interface. This is to get a full view of the interfaces file.
This might add some overhead. Should not change anything during boot.
Still looking at ways to optimize.

This has left some dead code in. cleanup comming in subsequent patches.
ip batch support is not complete. It currently works only for mstpctl
bridges. more coming ..

These are executed with shell=True and python subprocess performance
with shell=True sucks. This seems to have improved in python3. Will try
that out next. And also plan to make this controllable via an option.
This reduces time to ifup by half.

- Moved link config to base ifupdown. I had been debating about this,
this is need to support manual and also the --no-scripts option.
- helps executing only link up/down operations if needed on an interface
- While at it, i also moved the scheduler methods to be classmethods
instead of instance methods (which again was a pending cleanup task)

- THe down sequence in the new ifupdown was causing switchd some grief
(wilson is looking at it). readded the topological sort which i had
removed in favor of only walking the tree. With the fix,i dont see the
switchd problem anymore.
- And another down bug was causing the bond to go away prematurely (only
with the all depends option). Added a upperdevice list to track upperdev references

still debating on the default behaviour for following dependents.
for now not following dependents might be better.
When all interfaces are selected, it always follows dependents
