Add OpenStack Keystone V3 support (#4889)

Keystone V2 is deprecated in favour of V3. This adds the necessary
connection parameters for establishing a V3 connection. Connections
to V2 endpoints are still possible and the configuration should
remain compatible.

This also introduces a SWIFT_REGION variable for multi-region
OpenStack environments and a SWIFT_CACHE_TTL that controls how long
tokens and other meta-data is cached for. Caching tokens avoids
rate-limiting errors that would result in media uploads becoming
unavailable during high load or when using tasks like
media:remove_remote. fog-openstack only supports token caching for
V3 endpoints, so a recommendation for using V3 was added.

# Swift (optional)
# For Keystone V3, the value for SWIFT_TENANT should be the project name
# Keystone V2 and V3 URLs are supported. Use a V3 URL if possible to avoid
# issues with token rate-limiting during high load.
# Defaults to 'default'
# Defaults to 60 seconds. Set to 0 to disable
# Optional alias for S3 if you want to use Cloudfront or Cloudflare in front
