[keycloak-dev] infinispan as a storage mechanism

[Bill Burke]

This is something I've been doing off and on for awhile.  An hour here
or there.  Its a lot of monotonous work.

Well worth it IMO if our build times drop drastically.  30 min build
is becoming burdensome.  If the console tests get turned on combined
with all the other tests that are added daily, I can see this turning
into 60 min by the end of the year.  Not to mention when I run a
single test from the IDE it takes like 10 seconds to start.  I'm just
sick and tired of it.

For migration, if you base your stored objects on Maps, you only have
to worry about cases where you're modifying objects that are
serialized.  These would need to be versioned as per java
serialization.  New things
