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.

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.

- Set bridge ipv4 address when bridge is present
- IPv6 changes for bridge
- Convert unit tests to the new model

- 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.

Remove the need for watching for IPAM data
structures and add multi store support code and
data reorganization to simplify address space
management.

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.

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.

- also provided a new utility to compute the
host part ip address which is resilient to
input passed in different representations.

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.
- At Handle creation, first check if an instance of the
the respective object is already present in the datastore.
- Handle sequence must be saved only if commit
to datastore is succesfull
- Caller (ipam) needs to manage the retry

- Handle contains sequence and identifier.
This way datastore integration can be done
at bitseq level.

- In order to facilitate usage of datastore
- This makes it slower. Efficiency will be
revisited later after datastore integration
is done.
