For development environment (cluster_run), couchdb logger level is info and not debug like for all other loggers

When starting a development environment via cluster_run, the couchdb logger log level is info and not debug. This contrasts with all other loggers such as 'ns_server', 'views', etc.

Start cluster_run, connect via a shell:

$ ./install/bin/couchbase-cli server-eshell -u Administrator -p asdasd -c localhost:9001

(n_1@192.168.1.80)1> ale:get_loglevel(couchdb).

{ok,info}

(n_1@192.168.1.80)2> ale:get_loglevel(ns_server).

{ok,debug}
(n_1@192.168.1.80)3> ale:set_loglevel(couchdb, debug).
ok
(n_1@192.168.1.80)4> ale:get_loglevel(couchdb). {ok,debug}

By default, to be consistent with all other loggers, couchdb log level should be set to debug level.
