New Module: nfsexport

Hi all,

I’ve (co)written a new module, nfsexport, for working with nfs export entries in /etc/exports.

https://github.com/randynobx/ansible-modules-extras/blob/devel/system/nfsexport.py

I plan on submitting a pull-request to the extras repo in the very near future. Any feedback would be welcome.

Thanks,
Randy
