login(s) using various authentication methods, bind credential
types, and connection encryption mechanisms
The tests cover various possible combinations of the following:
* Authentication method: Anonymous or Simple (default),
* Bind credential: Secret (default) or Vault,
* Connection encryption: Plaintext (default), SSL, or startTLS
Also, ignore the StartTLS LDAP tests for now till KEYCLOAK-14343
& KEYCLOAK-14354 are corrected (due these issues they aren't
working with auth server Wildfly). They will be re-enabled later
via KEYCLOAK-14358 once possible
