[keycloak-dev] new deployer in master

[Bill Burke]

Ok,

New provider deployer exists in master.  You can package components in 
any type of deployment.  i.e. within a EAR or WAR. Hot deploy works as 
well.  The deployers/ directory and deployment-scanner subsystem is now 
back in the server.  Also added JTA transactions.  So, now when a 
KeycloakSession is created a new JTA transaction is associated with the 
KeycloakTransactionManager.  If there was an existing JTA transactionn, 
that transaction is suspended and resumed after the keycloak session 
completes.  JTA TransactionManager lookup has an SPI now which you can 
enable/disable in keycloaks-server.json.  If no transaciton manager 
exists i.e. within the testsuite, JTA is not used at all.

I'll be documenting all this eventually.  Still have some work to do on 
the new user federation spi before that though.
