Jana Radhakrishnan 89e72d8888 Remove kvstore deps from datastore package
Currently datastore has dependencies on various kv backends.
This is undesirable if datastore had to be used as a backend
agnostic store management package with it's cache layer. This
PR aims to achieve that.

Alessandro Boch dc4285b9a4 Adjust ipam errors
- Remove from contract predefined errors which are no longer
  valid (ex. ErrInvalidIpamService, ErrInvalidIpamConfigService)

- Do not use network driver error for ipam load failure in controller.go

- Bitseq to expose two well-known errors (no more bit available, bit is already set)

- Default ipam to report proper well-known error on RequestAddress()
  based on bitseq returned error

- Default ipam errors to comply with types error interface

Alessandro Boch 90711b0def Fix bug in bitsequence.pushReservation
- pushReservation fails to correctly detect when
  the affected block is the last in the current
  sequence. It thinks instead the block is in between
  the sequence. Because of this a couple of issues
  may happen:
   1. The allocation of the last bit causes the creation
      of a phantom sequence (length 0) at the end.
      (This has no side effects).
   2. The allocation of a bit somewhere in the middle of
      the bitmask may lead to a completely incorrect
      sequence pattern.

David Calavera cc02894a50 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.

Alessandro Boch 5034c9bb11 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.
