ebd673e976 tests/krb5: Allow expected_error_mode to be a container type
This allows a range of possible error codes to be checked against, for
cases when the particular error code returned is not so important.

3330eaf39c tests/krb5: Remove harmful and a-typical return in as_req testcase
A test in a TestCase class should not return a value, the
test is determined by the assertions raised.

Other changes will shortly cause kdc_exchange_dict[preauth_etype_info2]
to not always be filled, so we need to remove this
rudundent code.

This also fixes a *lot* of tests against the MIT KDC

b7b62957bd initial FAST tests
Currently incomplete, and tested only against MIT Kerberos.

[abartlet@samba.org
 Originally "WIP inital FAST tests"

 Samba's general policy that we don't push WIP patches, we polish
 into a 'perfect' patch stream.

 However, I think there are good reasons to keep this patch distinct
 in this particular case.

 Gary is being modest in titling this WIP (now removed from the title
 to avoid confusion). They are not WIP in the normal sense of
 partially or untested code or random unfinished thoughts. The primary
 issue is that at that point where Gary had to finish up he had
 trouble getting FAST support enabled on Windows, so couldn't test
 against our standard reference. They are instead good, working
 initial tests written against the RFC and tested against Samba's AD DC
 in the mode backed by MIT Kerberos.

 This preserves clear authorship for the two distinct bodies of work,
 as in the next patch Joseph was able to extend and improve the tests
 significantly. ]
