Introduce cache.memory_ratio configuration for HPCache

New set-and-forget configuration that specifies cache size as a ratio of the
old generation max size. Memory division across internal components of the cache
is handled by fixed ratios.

If any of the old config (now referred to as "advanced config") is set, it will
override the memory_ratio configuration.
Everything not starting with 'cmdchar' is cypher.

* Also remove old debug message
Cleanup EideticRequestMonitor
Improvements to the application pause monitor.

- Use System.nanoTime() to remove false-positive from network time adjustments
  and other external factors.
- Don't track total block time, It isn't a useful metric and it was confusing.
- Have the "trigger" level be the max block time that's acceptable, rather than
  the max block time plus the monitor pause interval.
- Bump the default block time trigger level to 200ms
- Introduce a manual mechanism to verify that the monitor works.
Log when property chains have duplicates

* Introduces the cappedLogger in StringLogger.
* Add a PropertyChainVerifier that checks the consistency of property chains as
  they are loaded.
* Add a PropertyChainVerifier implementation that logs when it finds
  duplicates.
Introduces CC check for duplicate property indexes in a given property chain

The check happens on first property checks, which then traverses the whole
 chain, recording duplicates
Adds a new report error in ConsistencyReport for the new type of inconcistency

As a note, this is a slight bending of the CC framework. It is the first check
 that requires state, whereas all previous cases required single record access
 only. Whether we change CC to accomodate this or we add a new type of "stateful"
 checks, that remains to be seen.

Moves logging for the runtime detector to be a responsibility of NodeManager,
 via an Observer pattern

[2.1] Detect duplicate properties
ParallelBatchImporterTest should have a test for the writer factory enabled by default

Details:
 - make sure we test the default configuration in ParallelBatchImporterTest
 - refactor to allow to test all the possible configuration
 - disable the test with IoQueue due to a known issue in parallelizing I/O writes
 - make package protected the constructor used only for testing
Improved comments in doImport
Make Funnel independent from IoQueue
Improved test
Remove unused File from the WriteFactory.create

- cleanup IoQueueTest

Fixes an issue with high id being too high after recovery

due to giving the IdGenerator the wrong highId in its constructor. It used
to give it fileSize/recordSize, but now gives it the highest inUse record id.

Also deduplicated 3 versions of rebuildIdGenerator, 2 versions of
figureOutHighestIdInUse (which was badly named btw) and some other
deduplication.
