HIBERNATE_SEQUENCE db object

[ChristosMylonas]

The HIBERNATE_SEQUENCE sequence oracle db object should be added in documentation as without it nothing actually works and NHibernate doesnt actually tells the reason.

This applies only when you create DB objects manually instead of leaving Hangfire.FluentNHibernateStorage do the database update.
Posting it here as an issue for anyone stump into this in future.

CREATE SEQUENCE "HIBERNATE_SEQUENCE" MINVALUE 1 MAXVALUE 999999999999 INCREMENT BY 1 START WITH 1 CACHE 20 NOORDER NOCYCLE NOPARTITION ;
