ISPN-4396 DSL Query right condition lost

The right condition of an OR or AND subcondition nested inside an outer NOT condition is lost because BaseQueryBuilder.not(FilterConditionContext fcc)
does not properly determine the root of the nested subcondition.
ISPN-4420 Allow configuring keepalive for hotrod connections
- fixed test
ISPN-4112 RHQ library plugin: restart cache -- availability report DOWN
but cache running

* Added back in availibilty down for cache not running
* Added server changes to also report DOWN when cache not running
ISPN-4265 Make it possible to deploy c3p0 in OSGi
ISPN-4276 Make JPA cache store work in Karaf
ISPN-4422 Packages with custom classes are not exported properly for HotRod tests in OSGi

* change access protocol to http-remoting-jmx for WildFly
Extract constant
ISPN-4416 Implement sorting and pagination for non-indexed querying (phase I)

This is a simple implementation that sorts all the results just before returning them to the requestor. A second implementation will be provided based on ISPN-4358 when it becomes available.
Most of the failing non-indexed query tests are solved by this.

* Also adds *QueryDslconditionsTest.testInvalidEmbeddedAttributeQuery() to prove ISPN-4423 happens only in remote lucene based mode, but not in the other modes
* Add param validation and tests for pagination for both indexed and non-indexed sorting
ISPN-4425 Validate format of comparison operands (non-indexed query)

* Validate operand format for numeric properties
* Validate operand for embedded entities -> do not allow such predicates
ISPN-2956 Hot Rod conditional operations and transactional caches

* Transactional caches are required in order to be able to guarantee
correct retry logic for Hot Rod operations relying on conditional
operations, or operations where the previous value is returned.
* WARN messages have been added for when conditional or operations
needing previous value are executed against non-transactional caches.
* Documentation updated with a section on Java Hot Rod client failover
capabilities and its effects on conditional operations.
ISPN-4372 Map/Reduce performance is dependent on cache value size
ISPN-4440 Remove setMaxCollectorSize API from MapReduceTask
