Feature/expose modules for logging

[richabindra]

This PR addresses Issue #156. A module option is added to the builder, so logging can be added at the application level if needed.

@cdancy - I copied the logging example from jenkins-rest wiki and created a Wiki for bitbucket-rest. I am not sure whether it needs to be added or not. Could you please advise?

[cdancy]

Code LGTM. Yeah not sure if you can just clone the wiki over or if it will come with the branch. @martinda do you remember how you did this?

[martinda]

The documentation is on a different upstream, in this case it would be https://github.com/cdancy/bitbucket-rest.wiki.git and it is not possible to use pull-requests, so for jenkins-rest I had to push directly to the cdancy user space. I had to push to master directly, and correct mistakes by pushing fixes.

@richabindra Thank you for providing the wiki and the code. Regarding the Wiki, it will need to be updated after this PR makes it to a release in order for the examples to use the right version numbers. Also I suggest you run all the code in the examples to make sure they are accurate.

[richabindra]

Ran the code in the examples as @martinda suggested. The example was tested by setting the version of bitbucket-rest to 2.2.1-SNAPSHOT locally, and is published with version set to 2.2.1.

@richabindra thanks for the PR! I can kick an new patch release ASAP if you want one. Just let me know.

[richabindra]

@cdancy - yes, a new patch release would be great! thank you :)

[cdancy]

@richabindra version 2.2.1 is now available.

[richabindra]

@cdancy - thank you.. appreciate the quick response :)

[cdancy]

@richabindra you're welcome and no problem.

[richabindra]

@cdancy - I tried pushing wiki page directly to your repository, but I am getting permission denied (obviously, but I just wanted to try). How do you want to go about moving wiki to your space?

[cdancy]

@richabindra try again. I just opened things up to allow anyone to edit.

[richabindra]

@cdancy - done. thank you. I have added logging page to wiki. Please review and let me know if there is anything that needs to be fixed..

[cdancy]

@richabindra nope that looks great and thanks for adding it.
