Neutron server logs are too big in the gate jobs

[Slawek Kaplonski]

As per email http://lists.openstack.org/pipermail/openstack-discuss/2020-August/016579.html we should not log all time-cost entries in the server logs for every job.
Maybe we can do it only in the rally based jobs and disable it everywhere else?

According to the mail, this https://review.opendev.org/#/c/730879/ should be reverted.

IMO, there are tons of resource extend calls during API/RPC request.

    Log time of the apply_func only if it took more than 0.1 second

    It seems that logging start and end time of the
    neutron_lib.db.resource_extend.apply_func function is little bit too
    much for e.g. our gate as neutron-server logs are huge in such case.

    So lets use directly oslo_utils.timeutils.time_it() function and log end
    of such calls only if it will take more than 0.1 seconds. If function
    was executed in shorter time, it isn't really necessary to have it
    logged.
