Jana Radhakrishnan 8c8bcffc56 Check if address space valid in getStore
Added a check to see if address space is valid in
addrSpaces map before accessing it. Also fixed some
error strings so that it provides better information
to the user.

Jana Radhakrishnan 845ef40a45 Make bridge driver networks persistent
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.

Alessandro Boch e78829b007 Fix in handling aux addresses
- libnetwork should reserve only the auxiliary
  addresses which belong to the container
  addresable pool. And should fail the network
  creation if the aux addr does not belong to
  the master pool.

Madhu Venugopal 7f53263551 ipam must honor preferedIP ahead of random allocation from subPool
Currently the default ipam implementation ignores the prefered ip if the
request is made on an existing sub-pool. The priority should be other
way around.

David Calavera 3afcd65d6e Move test specific functions to a testutils package.
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.

Spike Curtis e2a63dff5a Datastore handles creating objects atomically.
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.
