Update percolate.asciidoc

fix typo
[TEST] Wait for shards to be allocated before running testUpdateMappingDynamicallyWhilePercolating.

If the percolate request is executed soon enough, all shards fail and the
mapping is not actually updated.
Switch back to ConcurrentMergeScheduler

Load tests showed that SerialMS has problems to keep up with
the merges under high load. We should switch back to CMS
until we have a better story to balance merge
threads / efforts across shards on a single node.

Closes #5817
[DOCS] Update merge docs to reflect the max_merge_at_once property
[TEST] Don't delete data dirs after test - only delete their content.

Closes #5815
Remove garbage
[TEST] Wait for green, and refresh after indexing in percolator test
[TEST] Fix PercolatorTests#testSimple2

This test requires a mapping since otherwise if there is no mapping
added the percolator query might not be parsed as a query on a numeric
field since the query might arrive on a node before the dynamic mapping
reached that node.

This commit also moves the `indexService.readAllowed()` call up before
the number of percolation queries is check to make sure we fail if reads
are not allowed - there might be a query in-flight which means we need
to check another node rather than return an empty result.
Better deal with invalid scroll ids.

Closes #5738
[TEST] Reduce the amount of docs being indexed.
add debug logs if failed shards can not be resolved.
Ensure close is called under lock in the case of an engine failure

Until today we did close the engine without aqcuireing the write lock
since most calls were still holding a read lock. This commit removes
the code that holds on to the readlock when failing the engine which
means we can simply call #close()
[TEST] catch exceptions if TTL already expired when indexing

TTLPercolatorTests indexes docs with small TTLs which can trigger
AlreadyExpiredException exception. This is expected while rare and
we should just catch them.
[TEST] Ignore bogus system properties.

LuceneTestCase might reset some solr properties that cause
our tests to fail if the run before in the same JVM We just ignore
solr properties.
Update multi-match-query.asciidoc

Typo
[Test] InternalEngineTests: increased gc deletes interval & turn it off randomly
Added version constants for 1.1.2 and 1.0.4
[TEST] make testTimeoutSendExceptionWithDelayedResponse more reliable on slow systems
