[feat] Remove bigcouch nagios leftovers

When migrating from bigcouch to couchdb, we need to remove leftover nagios
tests for bigcouch.

- Added new classes: site_check_mk::agent::couchdb::bigcouch and
  site_check_mk::agent::couchdb::master

- Tested: unstable.pixelated-project.org
- Resolves: https://github.com/pixelated/pixelated-platform/issues/126
