backend plugins: fix crashes in development mode

Do not set or delete attributes directly on KerberosWSGIExecutioner, ldap2
and ra_lightweight_ca instances, as that raises an AttributeError in
development mode because of ReadOnly locking.

Use the usual workaround of `object.__setattr__` and `object.__delattr__`
to fix the issue.
