Subject [Impala-CR](cdh5-2.6.0_5.8.0) IMPALA-3577, IMPALA-3486: Partitions on multiple filesystems breaks with S3_SKIP_INSERT_STAGING

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.

All jobs with HDFS as the default filesystem need to set the
appropriate environment for S3, i.e. the following:
 - export AWS_SECERT_ACCESS_KEY
 - export AWS_ACCESS_KEY_ID
 - export S3_BUCKET

The FILESYSTEM_PREFIX will be set by the test to allow S3 to be used
as the secondary FS.
