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.

8e69328c3b BitSequence should unmarshal data during get
When bit sequence is trying to get key/value from the
data store it should always unmarshall the json data
before using it, as the data is JSON marshalled before
storing it in the data store.

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.

  the respective object is already present in the datastore.
- Handle sequence must be saved only if commit
  to datastore is succesfull

c603907331 Add bitseq package
- Initial version
- It allows handling reservation/release of a finite set
  of resources through large bitmask.
- It represents the bitmask as a list of equal
  consecutive 32 bits long bitmask symbols.
  It basically operates on a run-length encoding
  of the bitmask without encode/decode processing.
