ALL option handling in the parser makes the syntax check fail

Overview of the issue

Since the all option is handled now as a NAME token. The syntax check is now failing because since this is a NAME token and because of the entityList rule in the parser, it tries to check the name syntax as a entity name. However ENTITY_NAME_PATTERN does not match all making it fail.

Motivation for or Use Case

When the jhipster-core is linked to the generator, the tests fails in the generator due to a test using a jdl containing service all with serviceImpl.

Reproduce the error

Link the jhipster-core (master) on the generator-jhipster (master) and launch the generator tests.

Suggest a Fix

Either revert the all handling back or add the edge case of all option in the syntax checking but we might need to fix some other problems too.
