v2.1 list-host support 'service' filter but v2 does not

[Ghanshyam Mann]

v2.1 list host support 'services' as filter but v2 does not. This makes difference between v2 and v2.1.

We need to make v2.1 same as v2 by removing that filter from v2.1. This can be added as microversion if required.

    Fix v2.1 list-host to remove 'services' filter

    In v2.1, list-host supports 'services' filter also
    But this is not case with v2 API. v2 list-host does not support
    'services' filter.
    v2.1 APIs should be same as v2 in all cases/scenarios.

    This is bug fix so not putting as microversions, its just a change to
    the v2.1 code so it is equivalent to v2. If later needed then, this can
    be reverted back as current ways via microversion.

    This was no best test coverage to catch this kind of issue.
    This was caught while merging the v2 and v2.1 tests
