This also needs to be changed to /var/log/tidb/slowlog.

Good catch.
BTW, this is kind of a code smell but I can't figure out a better solution. I'll document this caveat or any better ideas?

I mean user may override the configuration by setting tidb.config

I think we can specify the command line argument -log-slow-query of tidb-server, Its priority is higher than the configuration file.

We should specify a request. Very few resources should be needed for this.

Is cpu 20m and memory 5MB a good default for both limit and request? (I've tested locally and seems that 10m cpu, 1MB memory is fairly enough)

I would not use a limit or make the limit a bit higher at least until we have observed it in production..

Agreed, maybe 50Mi memory limit is enough. This is pretty small comparing to TiDB itself.

* Support slow log tailing sidcar for tidb instance
Arbitrary mount point given by user may be harmful, so we don't allow customizing the slow-query-log file location.
close #231
