Infinispan JDBC cache stores missing read/write attribute operations for legacy attributes

In EAP6, the following commands were valid:

/subsystem=infinispan/cache-container=foo/local-cache=bar/string-keyed-jdbc-store=STRING_KEYED_JDBC_STORE:read-attribute(name=datasource)
/subsystem=infinispan/cache-container=foo/local-cache=bar/string-keyed-jdbc-store=STRING_KEYED_JDBC_STORE:write-attribute(name=datasource, value=java:jboss/datasources/ExampleDS)

In EAP7, these commands result in "Unknown attribute" errors. Even though the "datasource" attribute was deprecated in EAP7, these operations should still work, and should return a value translated from the "data-source" attribute.
