Tweak a CassandraThrift pool default setting

This int setting tweak should actually have no effect, since the
boolean that controls whether it is read is still false.
Refactor assemblies to support Hadoop1/2 specifica

Now that we have a pair of archive zipfiles, one with Hadoop 1 and the
other with Hadoop 2, the mapred-site.xml and core-site.xml files that
we ship in conf should be version-appropriate.  Pretty much all
interesting config keys changed between 1.x and 2.x, so we can't just
share files without generating a bunch of deprecation warnings under
Hadoop 2 and inviting confusion/mistakes.

Now the Hadoop 1 and Hadoop 2 distro modules each have their own
copies of the mapred-site.xml and core-site.xml files.  The mechanism
is more general -- any files or directories in
titan-dist-hadoop-{1,2}/src/assembly/static/ will appear in their
respective archive files.

Temporary fix for relative ES directory, conf-file

Relative paths for ES's directory and conf-file options used to be
interpreted relative to the config file in which they appeared, same
as storage.directory and storage.conf-file, but this broke a while
back.  It only broke for indices though -- not storage backends.

This commit is a short-term fix that restores the old interpretation
for indices.  The code this commit touches is a relic from the days of
hard-coded string config keys and should be refactored out of
existince by extending ConfigOption.
Make Faunus copy DistributedCached'd jars to HDFS

Hadoop automagically copies files and creates symlinks when adding
jars to the DistributedCache under the local JobRunner, but Hadoop
requires the user (Faunus, in this case) to manually copy jars from
the local filesystem to HDFS when using an actual cluster.  This
commit extends AbstractDistCacheConfigurer and its subclasses to
address both cases instead of just working in the local case.
Fix outdated config keys in reindex tests

Replaced hardcoded strings with references to ConfigOptions and calls
