I think the --tgt-kinit-attempts approach is good one. Couple comments I have
when reading the patch:
1) Function
+def get_host_tgt(options, keytab, host, realm, env):
should be made more general purpose and instead of whole "options", it should
rather accept just "kinit_attemps". It will then enable future generations to
reuse the function for something else. Just a generally good practice, nothing
critical.
2) I think
+ if returncode == 0:
+ root_logger.info("Attempt %d succeeded." % n_attempts)
+ break
can be just DEBUG level. People do not need to know we will try multiple
attempts.
3) It may be even better to print
"Attempt %d/%d failed." instead of just number. But this is up to you.
4) I see several C-isms in the code, as a programming practice, let us remove
them :-) In Python, the OK/notOK status is generally passed via exceptions, not
return codes unless you really need them for anything meaningful.
So, you can omit "raiseonerr=False" and have the handling code in an Except
clause. When max number of attempts is breached, you then just raise the
exception further (use bare "raise", to re-raise to keep the original stack).

Additionally:
5) I would prefer if the option was named --kinit-attempts instead of
--tgt-kinit-attempts (the "tgt" seems redundant).
6) Please do not use backslashes for line wrapping, unless it is
absolutely necessary. Instead, enclose the expression in parens for
implicit continuation:
+ help=("number of attempts to obtain host TGT"
+ "if the first one fails (defaults to
%default)."))
7) Please follow PEP8 in new code:
