[keycloak-dev] more db schema changes

[Bill Burke]

* created @NamedQuery for every creatQuery we have
* Use @Column, @JoinColumn, and @JoinTable, and @Table everywhere. 
names are uppercase with "_".  At least 10+ years ago, this was the 
standard naming convention.
* CredentialEntity now has a generated String ID.  We will want to have 
multiple TOTP entries in the future.
