cubicweb #343611 db-create should validate user input [open]

Some non-critical tracebacks could be avoided by some validation checks and an appropriate message in the db-create command to prevent bad user experience.

Exemple:

  • database name format (dash not accepted)
  • duplication of login between cubicweb manager and database user
  • db password should not be empty when using unix socket
