Fixed python load paths so that vppcfg will work installed as python
library and standalone from the source directory, fixing load
pathes for resources such as yaml files along the way.
Added a make target for pylint called 'make check-style', fixed a
number of minor pylint issues along the way.

This requires a schema change, adding 'mode' and 'load-balance' fields,
a semantic invariant that 'load-balance' can only be set in the case of
LACP and XOR bonds, a mapper from the mode/lb strings, ie.
"round-robin" to their VPP numeric counterparts, a bunch of unit tests.
Then in the reconciler, changing bonds (__bond_has_diff()) will
invalidate any LCP or sub-interfaces built on them, so those will have
to be pruned. create_bondethernet() will now create (or re-create)
the bond with the correct flags.
Unit-tests, YAML tests and the integration test all pass.
Updated config-guide.
Bridges can be created with default settings, with specific settings,
and they can be sync'd at runtime with all of the settings in this
change.
Notably missing are two features:
- unknown unicast flooding into specific interfaces (as opposed to
on/off on the bridge)
- learn-limit, which does not have an API getter, only a setter.
