[WFLY-3667] Remove EJB default permissions concept

As per https://issues.jboss.org/browse/WFLY-3667 I think introducing these permissions was an error and is never desirable in a security manager situation.  This PR removes the permissions and makes the corresponding enable/disable attribute a no-operation.
We could, but for no real good reason that would break CLI users/scripts that set it to false. Unless you turn it off in jboss-cli.xml, the CLI validates the names of the params in an op against the list exposed in the resource metadata.
