Remove CA key password from cert setup

Password protection in the current implementation is not actually
applied despite the presence of the ca_password config
option. Password protection is of marginal benefit because the
password must be stored in a file using the same protections afforded
to the key file. Password protection currently is not utilized with
externally provided keys.

Remove the ca_password config option and remove the use of the various
password related options to the OpenSSL commands whose net effect was
not actually accomplishing anything.

See the bug report for a thorough description of the issues.

Fixes: Bug #1214016
Fixes for user response with LDAP user_enabled_mask

This fixes a couple of problems with the returned user object
when the Keystone server when the LDAP Identity backend is
configured and the user_enabled_mask setting is not zero.

First, the returned user had the masked value (e.g., 512) when
a user was created rather than the actual enabled value (true
or false).

Second, the Keystone server was returning the enabled_nomask
attribute in the user entry when users were listed or updated.

This change makes it so that the server returns the enabled
value as a Boolean when a user is created. Also, the
enabled_nomask attribute is not returned when users are
listed or updated.

Cleanup tests imports so not relative

This change cleans up the imports in tests packages by changing
relative local imports to absolute imports per OpenStack hacking
guidelines.

Move gettextutils installation in tests to core

gettextutils.install was done in tests/__init__.py, but this was
not consistent with how test environment setup is done. We have
code to set up the environment in core.py, so other environment
setup should be there. Also, this makes tests/__init__.py cleaner.
