``cmd.sanity.checks._get_ovn_version`` is returning a 3 element tuple, instead of 2

[Rodolfo Alonso]

The method ``cmd.sanity.checks._get_ovn_version`` is returning a 3 element tuple. The output of the "ovn-nbctl --version" and "ovn-sbctl --version" have three elements, in the format "major.minor.revision". E.g.:

  $ ovn-nbctl --version
  ovn-nbctl 21.06.0
  Open vSwitch Library 2.15.90
  DB Schema 5.32.0

The elements to be compared with should be a 3 element tuple too.

    ``_get_ovn_version`` returns a 3 element tuple

    The output of this method should be compared to a 3 element
    tuple.

    This patch changes the minimum versions of the supported
    features to have 3 elements too. This are the version changes
    and their justifications:
    * OVN_NB_DB_SCHEMA_GATEWAY_CHASSIS = '5.7.0'
      Version reported in LP#2008077
    * OVN_NB_DB_SCHEMA_PORT_GROUP = '5.11.0'
      Version reported in LP#1946023
    * OVN_NB_DB_SCHEMA_STATELESS_NAT = '5.17.0'
      Version reported in LP#1949494
    * OVN_SB_DB_SCHEMA_VIRTUAL_PORT = '2.5.0'
      Version reported in LP#1949496
    * OVN_LOCALNET_LEARN_FDB = '22.09.0'
      Version reported in LP#1946023. In fact, the version
      supporting this feature is older.
