Deprecate the "local" argument in CivisFuture()

[pcooman]

This PR address issue #244:

• updates the DESCRIPTION file:
  • increments the version tag to v3.0.1 (patch from v.3.0.0)
  • replaces Patrick Miller with @pcooman as the maintainer of the civis package
  • adds the lifecycle package as a dependency (to warn users of the new deprecated argument)
• in civis_future.R:
  • sets the local argument to be deprecated (+ in documentation)
  • raises a warning if a local argument is supplied
  • removes the deprecated local argument from future::Future()
• in scripts.R
  • removes @inheritParams fetch_output_file_ids. All arguments for fetch_output were already present, so this was raining a warning when building the Roxygen2 documentation.
• in civis_ml.R
  • I split the documentation for x, newdata, Because the documentation for x was not getting properly inherited into the documentation of the CivisML functions (this was causing an R CMD CHECK warning)
• updates all documentation (generated using Roxygen2 v7.2.2, up from v7.1.0)
• (almost) all files in the man folder were generated when I re-generated the default client (use run_generate_client.R in the tools directory)
• updates the CHANGELOG

I think this change is worth a minor version bump https://semver.org/

If you're bumping the version number in DESCRIPTION, I think you should add a [3.1.0] section here in the changelog also. Other than that, looks good
