add file/folder sharing feature

[raghav-dalmia]

I write a function a function name share() in action.py, which take file id as mandatory argument and role, type and message are it's optional arguments.

Following image show result of drive share --help

If type is anyone, it will generate a share link and print it, otherwise, it will take email id as an argument and share the link directly to grantee/user.

@raghav-dalmia other than changes said by @inishchith, make sure you code is pep8 compliant, cos I see a lot of errors on running flake8 test. Rest looks good to me.

[raghav-dalmia]

I fix my code using autopep8, please check. Sorry about this thing.

[inishchith]

@raghav-dalmia can you please sync your branch. As i see you've changes which are irrelevant to the task.
