openvpn: Add functional tests for user group "vpn"
This is the first functional test which tests the permissions of a
non-administrator user in a group.

Some changes had to be made in the form shown in users module for this
to work. The id of each checkbox in the "Permissions" section is now
predictable based on the name of the group. For example, the id of the
checkbox for the group "vpn" is `id_group_vpn`. Changes are also made in
`CheckboxSelectMultipleReadOnly` form class for consistency, though it
is not being used by this functional test.

Some utility functions for functional tests have been moved out of users
module to be usable by other app modules for testing group permissions.

One additional utility function to skip creating user if it already
exists has been added. Not using this function wouldn't break the test
but using it saves some time.

Changed password format string to use `S` instead of `w` to support
special characters in password.
