Merge branch 'trunk' into CASSANDRA-5519
Don't use key cache on index summary test CF
Use first, last keys instead of summary for sstable exclusion

Since the summary is no longer guaranteed to contain the first
partition in the primary index, checking for a -1 result from the
index summary binary search is not sufficient for determining that
a key isn't present.  The first and last keys for the sstable can
be checked instead.
Update unit tests for new space distribution policy
Tests for ISM JMX functions, minor fixes
