Change type for variables to bool

[ppieprzycki]

This commit will change variables commit_changes and replace_config to bool.
Also according to the doc string replace_config variable is not required but has default set to false.

After this change module will accept following values for mentioned variables:
yes,on,1,true,1,no,off,0,false,0

After this change module will not be backward compatible if someone used values "True" or "False" as in following example

msg: value of replace_config must be one of: yes,on,1,true,1,no,off,0,false,0, got: False

Hi!
The docstring mentions True and False for those parameters. Could you update the docstring to reflect what you mention in your PR message?

Thanks!

[ppieprzycki]

Just updated doctoring.
Added all possible combinations as choices.

Thanks! Will do some tests soon and approve the PR if I don't see anything wrong (I a sure I wont but better safe than sorry). I am still enjoying some days off so I guess I will take a look early next week : )

Hi! As you probably read here:

https://groups.google.com/forum/#!topic/napalm-automation/DI2w4s1vk9I

We have changed the organization and moved the ansible plugins to a dedicated repo. Would you mind closing this PR and sending a new one to the new repo? The reason why I prefer to do this is so your contribution is not lost during the movement.
