Since libnetwork is going to provide createNetwork
notifications only once when the network is created
bridge network needs to save it's network state in
persistent store so that it becomes available even
after restart.

Add local scope store caching support as
well as do some refactoring to make it datastore
scope aware and manage scope specific config.

This way we won't vendor test related functions in docker anymore.
It also moves netns related functions to a new ns package to be able to
call the ns init function in tests. I think this also helps with the
overall package isolation.

In that commit, AtomicPutCreate takes previous = nil to Atomically create keys
that don't exist. We need a create operation that is atomic to prevent races
between multiple libnetworks creating the same object.
Previously, we just created new KVs with an index of 0 and wrote them to the
datastore. Consul accepts this behaviour and interprets index of 0 as
non-existing, but other data backends do no.
- Add Exists() to the KV interface. SetIndex() should also modify a KV so
that it exists.
- Call SetIndex() from within the GetObject() method on DataStore interface.
- This ensures objects have the updated values for exists and index.
- Add SetValue() to the KV interface. This allows implementers to define
their own method to marshall and unmarshall (as bitseq and allocator have).
- Update existing users of the DataStore (endpoint, network, bitseq,
allocator, ov_network) to new interfaces.
- Fix UTs.
* Removed network from being marshalled (it is part of the key anyways)
* Reworked the watch function to handle container-id on endpoints
* Included ContainerInfo to be marshalled which needs to be synchronized
* Resolved multiple race issues by introducing data locks
