It was removed as part of improvements in [1]. But it seems it's
a different type/class of errors and should still be filtered
out here.
This time for all the services to avoid extra copies.

This is in the hope to avoid random "Unable to validate token" in
AIO upgrade jobs which restart the Keystone container while
other services are trying to use it (most notably Placement but
also Nova and Neutron).

Make it less likely to fail on false positives.

We consider them critical and prefer to fail the jobs.

It was seen in [1] and some other occassions, possibly neutron was trying
to fetch token while keystone was being upgraded.

We are getting this randomly on neutron-server shutdown
for upgrade.
As it does not affect real operations (and if it did,
we would definitely see it now), let's ignore it.

There is a number of critical log messages that we see in CI from time
to time. While these should be fixed, let's not fail jobs unnecessarily.

This change introduces one expected critical message in
placement-api.log:

    Failed to fetch token data from identity server

Also makes check-logs clear the aggregate files
to prevent duplicates due to upgrade and post.

This script has a few issues:

* It catches false positives, due to log levels in config options.

* It doesn't fail on CRITICAL logs, due to variable reset issue.

This change fixes these.

At the end of a CI run, check all log files.
