Let user specifiy tmp directroy for dump and import functions

[bigtree3131]

For users who's cluster will not fit in /tmp, this is a must.

parser.add_option("-d", "--tmp-dir", dest="tmp_dir", default=None, type="string")

def run_rethinkdb_export(options):
# Create a temporary directory to store the intermediary results
temp_dir = tempfile.mkdtemp(dir=options["tmp_dir"])

Thanks @bigtree3131 !

@Tryneus, does this seem reasonable?

[Tryneus]

Yeah, I can add this fairly easily.

[bigtree3131]

Thanks!

Ok, finally got around to this! This has been approved in review 1921 and merged to next in commit 8aa7ee1. Cherry-picked into v1.14.x in commit 7cb0b50. Will be in release 1.14.

Note for anyone using an older version of the python driver: since we use tempfile.mkdtemp, you can specify this using environment variables (see https://docs.python.org/2/library/tempfile.html#tempfile.tempdir).

Thanks for bringing this to our attention, @bigtree3131!

Cherry-picked this into v1.13.x in commit e1b5042, because it may be useful to people backing up their databases before upgrading to v1.14.0. This will be in release 1.13.4.

@bigtree3131: This fix is in RethinkDB 1.13.4, which we released today.

Awesome! Thanks @Tryneus
