v3.84.0

Changes since v3.83.1:

New features:

• Add support for third-party log forwarding integrations (API availability
  depends on the project): newrelic, sumologic, splunk, and syslog.
• Add metrics:disk-usage (disk) command.

Other changes:

• Use the API URL consistently to fetch a project even if a direct hostname is
  supplied. This deprecates the --host option (the option is still there but
  will be ignored).
• Bump composer/ca-bundle from 1.3.3 to 1.3.4 (#1170).
• Disable docker credential helper inside a container (where it does not work).
• Ensure Drush alias names only contain allowed characters. This fixes aliases
  for environment names containing a slash.
• Find the correct app's SSH URL when no instance or default is given.
