the various assert_ methods in guest_log_runners don't account for slow hosts

A common class of gate failures is as shown in attachment.txt

A poll with backoff would be advisable here.

    Improve Gate: address multiple issues relative to timing

    This commit merges two commits, 447750[1] and 448630[2] in the fond
    hope that this will improve the odds of its being able to merge.

    The log operation test assumes that the log will be Ready but in some
    cases, Partial is also a valid result. Add that into the list of
    allowed results.

    In addition, this change aims to support cases where test suites last
    much more than 1 hour and where a token can expire unexpectedly mid
    operation. This is by no means a 'fix' for the bug here, just a way to
    get the gate to be more stable.
