Add provision to tag a avocado framework and tests version

[sathnaga]

It would be good to have a way to use a tagged(release) versions of framework and tests
repository, so that we can tag version here aswell.

default can be always pointing to master but while we release tests version, it is good to have mention of the other known versions tagged aswell.

First, we need to add a provision to use the branch.

RHEL 8.2: (xyz)
100 tests (ran)
Avocado: 79
Avocado-vt:79
misc-tests: v1.2
tp-qemu: xyz
tp-libvirt: xyz

6 months

RHEL8.3: (abc)
140 tests(ran) - 50(added) - 10(removed)
Avocado: 81
Avocado-vt:81
misc-tests: v1.3
tp-qemu: abc
tp-libvirt: abc

@sathnaga @PraveenPenguin @harish-24 This one slipped out of the radar. Are we all still fine with getting a versioning for test repos and mapping / tagging ?

I think we can start tagging and mapping the test repository with framework then considering we already have the provision for installing a version of framework.
