Remove superfluous "Please refer to logs" from fail_msg

[Kyrylo Romanenko]

In test test_sanity_glance.py we can shorten failure message from
fail_msg = ("Image list is unavailable. Please refer to "
                    "OSTF logs for more information")
to
fail_msg = "Image list is unavailable. "
In other tests failure messages are quite laconic too.

Phrase "Please refer to OpenStack logs for more details." will be appended to error message by method verify_response_true() in case of test failure.

    Remove superfluous text from fail_msg

    Phrase "Please refer to OSTF logs for more details." is superfluous
    in fail_msg, because such kind of text is appended to an error message
    by method verify_response_true() in case of test failure.
