Based on the pattern design from puppetlabs modules I
added some new classes to make the  functionality more self-contained
(mongodb::server,  mongodb::install, mongodb::config, mongodb::repo, etc).

Also the major change is the introduction of the mongodb::globals
class which should be used for node/server specific settings,
which could be the same for various mongod instances on the same server.

The main mongodb::server class has similar API than the current mongodb,
with extra parameters to cover new mongod functionality.

New parameters:
 - verbositylevel
 - quotafiles
 - diaglog
 - directoryperdb
 - profile

Furthermore the mongodb class was modified to use the new mongodb::server
class so that the current module users who uses the default parameters
values should be able to upgrade without any changes. More testing
needed.

Rspec-puppet tests mostly focus on mongodb config file
so some additional tests should be added for extra safety.

System tests cover mongodb server installation with default
mongodb package (EPEL for Redhat osfamily) and  10gen/mongodb
repository. Most standard use cases are covered. Again I recommend
adding some extra tests, after the module is finalised.

Refactor of the module

Added a sleep to one of the system tests to give the Mongo
server enough time to start up. Made port parameters consistent
across classes.
