* Support JSON lists for Okta user groups+policies.
Migrate the manually-parsed comma-separated string field types for user
groups and user policies to TypeCommaStringSlice. This means user
endpoints now accept proper lists as input for these fields in addition
to comma-separated string values. The value for reads remains a list.
Update the Okta API documentation for users and groups to reflect that
both user group and user/group policy fields are list-valued.
Update the Okta acceptance tests to cover passing a list value for the
user policy field, and require the OKTA_API_TOKEN env var to be set
(required for the "everyone" policy tests to pass).
* Fix typo, add comma-separated docs.
This removes all references I could find to:
- credential provider
- authentication backend
- authentication provider
- auth provider
- auth backend
in favor of the unified:
- auth method
* Adding support for base_url for Okta api
* addressing feedback suggestions, bringing back optional group query
* updating docs
* cleaning up the login method
* clear out production flag if base_url is set
* docs updates
* docs updates
