Sailesh Mukil 6f1fe4ebe7 IMPALA-3577, IMPALA-3486: Partitions on multiple filesystems breaks with S3_SKIP_INSERT_STAGING
The HdfsTableSink usualy creates a HDFS connection to the filesystem
that the base table resides in. However, if we create a partition in
a FS different than that of the base table and set
S3_SKIP_INSERT_STAGING to "true", the table sink will try to write to
a different filesystem with the wrong filesystem connector.

This patch allows the table sink itself to work with different
filesystems by getting rid of a single FS connector and getting a
connector per partition.

This also reenables the multiple_filesystems test and modifies it to
use the unique_database fixture so that parallel runs on the same
bucket do not clash and end up in failures.

This patch also introduces a SECONDARY_FILESYSTEM environment variable
which will be set by the test to allow S3, Isilon and the localFS to
be used as the secondary filesystems.

All jobs with HDFS as the default filesystem need to set the
appropriate environment for S3 and Isilon, i.e. the following:
 - export AWS_SECERT_ACCESS_KEY
 - export AWS_ACCESS_KEY_ID
 - export SECONDARY_FILESYSTEM (to whatever filesystem needs to be
   tested)

TODO: SECONDARY_FILESYSTEM and FILESYSTEM_PREFIX and NAMENODE have a
lot of similarities. Need to clean them up in a following patch.
