Obsolete mongod options should be removed from the charm

[Mario Splivalo]

There are several options in mongodb charm which are obsoleted in mongodb. For instance:

If one enables 'nocursors' option (available in mongodb charm), mongod fails to start:

root@mario-local-machine-1:~# grep nocurs /etc/mongodb.conf
nocursors = true

root@mario-local-machine-1:~# mongod --config /etc/mongodb.conf
error command line: unrecognised option 'nocursors'
use --help for help

The option should be removed from the charm.

Actually, there are more options inside the charm that are not supported any more, for instance:

root@mario-local-machine-1:/var/log/mongodb# mongod --config /etc/mongodb.conf
error command line: unrecognised option 'mms-interval'
use --help for help

I'll get over all of them, list them here, maybe open a new bug for this, and fix the charm.
