Bugfixes:
* A debug display of server timing info was always enabled when it should have
been disabled by default. This produced extraneous output to stderr for some
commands.
* Fix bug causing `globus rm` to fail when using the `--dry-run` option.
Enhancements:
* Add `globus flows create` as a new command for creating flows.
* JSON file parsing throughout the CLI has been made more uniform and robust.
Commands which required files to be specified with the `file:` prefix now
allow for filenames without the prefix, improving tab-completion. All
commands which accept JSON data as inputs now allow for files or
JSON-formatted arguments.
* Add the `--local-user` option to the `globus ls`, `globus rename`, `globus mkdir`,
`globus delete`, and `globus rm` commands.
* Add the `--source-local-user` and `--destination-local-user` options to the
`globus transfer` command.
* Error reporting for parsing errors during `--batch` processing has been
improved to better indicate the source of the error
