Replace validate_email with email-validator

[bgermann]

validate_email seems to be abandoned. Please consider replacing it with the alternative module email-validator. This will help me packaging the latest crossbar version in Debian because validate_email does not have a chance to enter Debian.

ok, just to be sure, we're talking about

https://github.com/crossbario/crossbar/blob/71787f9eae220966e6be4a608cc049e336f9a85b/requirements-min.txt#L73

and thus replace

https://pypi.org/project/validate_email/ https://github.com/syrusakbary/validate_email

with the following

https://pypi.org/project/email-validator/ https://github.com/JoshData/python-email-validator

right?

Right. I guess they do not have the same API, so there would be additional changes.
