Don't use check_mk logwatch to watch bigcouch logs anymore (#7375)
The rationale here is: - bigcouch/its included erlang version is incredibly noisy and spits out warnings/error msgs all the time - it uses the worst logging format i ever saw, multiple lines directly to a file (couch 2.0 uses lager as logging backend which can log to syslog) - trying to sort out the false positives will take too much time, and who knows which of them will be resolved in couch 1.6/2.0 Change-Id: Idbe6b37a19cd65ce31a50d4c28eedb4cf15ba3b5
