Use the `all` matcher to check the existence of each path.

Bump mustache from 1.0.5 to 1.1.0 in /Library/Homebrew/test

Use cache_store for descriptions

This makes use of both the existing interfaces and could use the
existing cache file but we'll create a new one and cleanup the old one
to avoid issues and use a more consistent name.

This change allows us to remove the `RSpec/IteratedExpectation` rule from `.rubocop_todo.yml` as we no longer iterate over each path to check existence.

Note: We this PR didn't change the subsequent test checking for the negative expectations as this isn't part of the rule (see: https://github.com/rubocop-hq/rubocop-rspec/issues/278).

This saves an API call, and is more accurate, because the repo API
doesn't actually say whether forking is enabled, but this error message
does.

To do this, the original GitHub error message had to be accessible on
the GitHub exceptions.

GitHub seems to be discouraging forking private repositories[0]:

> By default, new organizations are configured to disallow the forking
> of private repositories.

bump-formula-pr tries to create its pull requests from a fork, so it
can't be used for private taps set up in this way.

I've added a --no-fork option that will create PRs in the tap repo
itself, rather than in a fork, to accommodate this use case.

Remove redundant check in formula_files and cask_files

Both formula_files and cask_files need to check whether a file is
a Ruby file. Also, use this method in formula_file? and cask_file?

Formula_files consists of every non-recursive child of formula_dir,
for which formula_file? evaluates to true. formula_file? checks if the file
is a child of formula_dir, which it is by definition. It turns out that by
removing the check, the time used for 'brew search' decreased from 800 ms to
700 ms, noticably faster during tab completion. The same happens with
cask_files and cask_file?

I'll step down on February 4th to better coincide with the Homebrew
