Allowing a dot to be part of the Organization's name and Members

[tulliobotti64]

What would you like to be added:

Allow the creation of an organization with a dot within its name. Example: dev.arch

The same is true for members. Allow members creation with a dot within its name. Example: [email protected]

Why is this needed:
To synchronize with Git and Papagaio (the new Agola's plugin)

@tulliobotti64 As far as I know also github (and perhaps gitea) don't allow dots in usernames/organizations since they could cause issues in path names in the ui/api and must be correctly handled in different special cases. We're currently using a regexp similar the to one used by github. Also @ isn't allowed in usernames in github/gitea/gitlab and I'd like to avoid permitting it.

So you should probably try to find a different mapping to avoid such kind of invalid names before trying to tighten the agola names restrictions.
