Tone down PingHandler too

By using https://github.com/ElasticPortalSuite/BungeeCord/commit/fd411edddb3a4821293d4afe37f368156ca2022b as base, this PR tones down the PingHandler too.

Reason for this is that some plugins (like mine) check the MOTD/playercount/... every X seconds for Y servers, making the log almost unreadable because of the spam.

Hope that fits in.
