Facilitate checking coverage counters from scripts and tests with a new
coverage/read-counter command that gets the total count for a counter.
Same could be achieved by scraping the output of coverage/show command
but the difficulties there are that output is in human readable format
and zero-value counters are not listed.

This commit changes the "ovs-appctl coverage/show" command to show the
the averaged per-second rates for the last few seconds, the last minute
and the last hour, and the total counts of all of the coverage counters.

I've had a few complaints that ovs-vswitchd logs its coverage counters
at WARN level, but this is mainly wrong: ovs-vswitchd only logs coverage
counters at WARN level when the "coverage/log" command is used through
ovs-appctl. This was even documented.
The reason to log at such a high level was to make it fairly certain that
these messages specifically requested by the admin would not be filtered
out before making it to the log. But it's even better if the admin just
gets the coverage counters as a reply to the ovs-appctl command. So that
is what this commit does.
This commit also improves the documentation of the ovs-appctl command.
