Title: CHEF-3531 allow dots in data bag names.  

Modify knife's regex for valid data bag names to include . as a valid character. Chef Server 11.x already seems to accept these names when making direct api calls to the data bag API.

I briefly considered excluding "special names" such as "." or ".." but since chef server accepts them as valid it seemed like the best idea would be to make knife's behavior consistent here.
