Can't run live system tests using testr

[David Stanek]

The move to testr has broken the ability to run the live system tests. Prior to testr they were run either directly by nose or through run_tests.sh. It seems that testr doesn't like the file names likely because the begin with an _.

To fix this I'd like to create a new location for system tests so that they can excluded from the default test run, but can be run by hand.

    Make LIVE Tests configurable with ENV

    To enable ldap live test, set the environmental variable
    ``ENABLE_LDAP_LIVE_TESTS`` to a non-false value.

    To enable tls ldap live test, set the environmental variable
    ``ENABLE_TLS_LDAP_LIVE_TESTS`` to a non-false value.

    To enable mysql sql live test, set the environmental variable
    ``ENABLE_LIVE_MYSQL_TESTS`` to a non-false value.

    To enable postgres sql live test, set the environmental variable
    ``ENABLE_LIVE_POSTGRES_TESTS`` to a non-false value.

    To enable db2 sql live test, set the environmental variable
    ``ENABLE_LIVE_DB2_TESTS`` to a non-false value.

    This allows for running all tests in a standard run by simply setting
    the appropriate environmental variables.

    This moves the live tests to be skips if the specific live-test
    environmental variables are not set.
