[CLOUD-1863] Add support for compatibility mode

[osnipso]

Issue: CLOUD-1863

Add support for configuring compatibility mode for each configured cache through the use of env.
Creates two new env variables:

${prefix}_CACHE_PROTOCOL_COMPATIBILITY

• Optional, can be set for each configured cache. Enables/disables compatibility mode. Default is disabled, "true" will enable it.

${prefix}_CACHE_COMPATIBILITY_MARSHALLER

• Optional, can be set for each configured cache. Marshaller for use in compatibility mode, only will be considered if compatibility mode is enabled though the previous env. As of JDG 7.1, does not support the configuration of external marshallers, only internal ones (e.g. org.infinispan.commons.marshall.JavaSerializationMarshaller or org.infinispan.commons.marshall.jboss.GenericJBossMarshaller).
