tools/glusterfind: kill remote processes and separate run-time directoriesv3.9.0rc2

Problem #1:
Hitting CTRL+C leaves stale processes on remote nodes if glusterfind pre
has been initiated.

Solution #1:
Adding "-t -t" to ssh command-line forces pseudo-terminal to be assigned
to remote process. When local process receives Keyboard Interrupt,
SIGHUP is immediately conveyed to the remote terminal causing remote
changelog.py process to terminate immediately.

Problem #2:
Concurrent glusterfind pre runs are not possible on the same glusterfind
session in case of a runaway process.

Solution #2:
glusterfind pre runs now add random directory name to the working
directory to store and manage temporary database and changelog
processing.
If KeyboardInterrupt is received, the function call
run_cmd_nodes("cleanup", args, tmpfilename=gtmpfilename)
cleans up the remote run specific directory.

Patch:
7571380 cli/xml: Fix wrong XML format in volume get command
broke "gluster volume get <vol> changelog.rollover-time --xml"
Now fixed function utils.py::get_changelog_rollover_time()

Fixed spurious trailing space getting written if second path is empty in
main.py::write_output()
Fixed repetitive changelog processing in changelog.py::get_changes()
