Defer tabOut.Flush

[edwinakatosh]

When running stolonctl status, i'm seeing the following output:

UID     HEALTHY PG LISTENADDRESS        PG HEALTHY      PG WANTEDGENERATION     PG CURRENTGENERATION
keeper0 true    10.1.0.36:5432          true            4                       4
keeper1 true    10.1.0.47:5432  true    2       2

instead of

UID     HEALTHY PG LISTENADDRESS        PG HEALTHY      PG WANTEDGENERATION     PG CURRENTGENERATION
keeper0 true    10.1.0.36:5432          true            2                       2
keeper1 true    10.1.0.47:5432          true            2                       2

@sgotti Please review and advise.

@edwinakatosh Thanks for the PR and sorry for being late.
We could clean it up without doing multiple defer but just doing a tabOut.Flush at the end of all the writing to tabOut in renderText and also remove the unused tabOut defined here.

I think i had tested that, but i'll confirm and update. Thanks @sgotti
