Remove leftover analysis environment variable

[r0x0d]

In the past, we introduced this environment variable to enable analysis when it was in tech preview. Since we are not in that stage anymore, the variable was left behind in the code after we started to remove all tech preview code.

The test failures seem unrelated, but want a second pair of eyes. @oamg/conversions-qe ideally one of you so you can see if there is new issues we should document somewhere

Yes it seems that there are unrelated errors like

>           assert False, "Unknown destination distro '%s'" % destination_distro
E           AssertionError: Unknown destination distro 'Red Hat Enterprise Linux release 8.10 (Ootpa)

and custom repos tests failures which should be now fixed under the https://github.com/oamg/convert2rhel/pull/1244 (which we just merged).

@Venefilyn, @r0x0d feel free to merge it
