Changes proposed in this PR:

This is the extension of the PR -
#2043

In this PR, the followings were addressed -

1. Now the vault enterprise version can be provided in the cli command. The previous PR only addressed Vault OSS.
2. Two flags “-no-cleanup-wan-fed” and “test-duration” were introduced to not to cleanup the test environment after successful setup to give it time to do manual testing for features/to reproduce customer issues. Default is 1 hour.

Update on July 14 on this - After the first review, the above flags are removed, instead a new flag "-no-cleanup" was introduced.

3. This was tested in Kind environment and it works fine. The following was placed back to use the “use-kind” option for WanFed test.

   if cfg.UseKind {
   t.Skipf("Skipping this test because it's currently flaky on kind")
   }
