Globus-cli

Bugfixes:

* Fix a bug in text output for `globus transfer --dry-run` which crashed with a
`KeyError` if `--external-checksum` was omitted

Enhancements:

* A new command, `globus flows list`, allows users to list Flow objects in
Globus Flows

* New commands for creating Globus Connect Personal endpoints and collections
** `globus gcp create mapped` creates a GCP Mapped Collection
** `globus gcp create guest` creates a GCP Guest Collection

In GCP, the Mapped Collection and Endpoint are synonymous. Therefore,
`globus gcp create mapped` replaces the functionality previously only available
via `globus endpoint create --personal`.

NOTE: Neither of the `globus gcp create` commands automatically installs Globus
Connect Personal on the local machine. These commands complement and interact with
an existing installation.

Other:

* `globus endpoint create` is now documented as deprecated. Users are
encouraged to use `globus gcp create` for Globus Connect Personal,
and the Globus Connect Server CLI for Globus Connect Server

* `globus endpoint create` no longer accepts `--no-default-directory` as an
option. It previously did nothing when used.

Enhancements:

* The globus CLI is now faster to start in many cases. Tab completions are most
significantly improved, but other commands may demonstrate an improvement as
well

* Add the `globus api timer` command for direct interactions with the Globus
Timer service

* Order `globus task list` by descending request time to prioritise
newer tasks in default output

Bugfixes:

* Fix `globus session update` help text not handling missing domain errors from Transfer

Enhancements:

* `globus group member invite` now supports provisioning new identities in
Globus Auth in order to support inviting new users who have not created
Globus accounts. Use `--provision-identity` to indicate that new users
should be auto-provisioned in Globus Auth

* Add new `globus timer` commands for interacting with the Timer service:
** `globus timer list` to list jobs
** `globus timer show` to show a particular job

* Add `globus search index delete` command

Enhancements:

* Commands which have required arguments will print their helptext if invoked
with no arguments. They still `exit(2)` (usage error). This only applies to
the case of a command with required arguments being called with no arguments
at all.

Bugfixes:

* Fix behavior of `globus api` to respect formatting options. `--jmespath` can
be used on results, and `-Fjson` will pretty-print JSON responses if the
original response body is compact JSON

Other:

* Increase the maximum width of help output to 80% of the terminal size.
* Remove support for python3.6 . Users on python3.6 should still be able to
install `globus-cli` but will not be able to update to the latest version.

Bugfixes:

* `globus endpoint activate --web` now correctly respects the environment when
it is set

Enhancements:

* Add a new command, `globus api`, which can be used to make requests to curl-like
requests to Globus services using the credentials from a globus-cli login
* Add commands for interacting with individual documents in Globus Search:
`globus search subject show` and `globus search subject delete`

Enhancements:

* New commands for interacting with Globus Groups
** `globus groups set-policies` to manage a group's policies
** `globus group member list` to list members of a group
** `globus group member invite` to invite a member to join a group
** `globus group member approve` to approve a member who has requested to join a group
** `globus group member reject` to reject a member who has requested to join a group
** `globus group invite accept` to accept an invitation to a group
** `globus group invite decline` to decline an invitation to a group
** `globus group join` to join a group, with an option `--request` for groups
which require approval for members
** `globus group leave` to leave a group
* `globus group member add` now supports the `--role` argument for adding
members with the `manager` and `admin` roles
* A new command for interacting with Globus Search,
`globus search delete-by-query` to bulk-delete data from a Globus Search index

Bugfixes:

* Fix an issue which caused certain commands like `globus mkdir` to retry
incorrectly when failing, leading to unnecessary delays on failure
