Allows keycloak 12 to be installed on Ubuntu 20

[typhonius]

• Allows a configurable timeout for jboss start as it took over 20 minutes on a test install. (This excessive startup time was MySQL operations running to alter tables etc)
• Allows configurable node mapping for standalone.xml as different versions of Keycloak use different namespaces
• Ubuntu 20 uses python3-lxml rather than python-xml

My host vars were:

keycloak_version: 12.0.1
keycloak_archive: keycloak-{{ keycloak_version }}.tar.gz
keycloak_url: https://github.com/keycloak/keycloak/releases/download/{{ keycloak_version }}/{{ keycloak_archive }}
keycloak_bind_address: "127.0.0.1"
keycloak_admin_username: "admin"
keycloak_admin_password: "snipped"
keycloak_create_admin: True
keycloak_mysql: True
keycloak_mysql_password: snipped
keycloak_python_lxml: python3-lxml
keycloak_srv_namespace: 'urn:jboss:domain:14.0'
keycloak_sub_namespace: 'urn:jboss:domain:datasources:6.0'
keycloak_jboss_timeout: "3600"

N.B. keycloak_jboss_timeout must be quoted as lxml.etree._setAttributeValue cannot use ints to alter attribute values in the XML.
