As previously discussed on [GitHub], this commit introduces a Cow-like
wrapper RegexRef to enable both `Regex` as well as `&Regex` as
arguments.
It also introduces a new module in the `build:arg` path to remove
clutter from the main module. For more information see #2073.

This commit introduces a new feature called `"regex"`. It adds a new
function `validator_regex` to `Arg` and was inspired by the discussion
in #1968. The name `validator_regex` was chosen instead of
`regex_validator` to make sure that the developer keeps in mind that
there may only be a single `Validator` on an `Arg`.
The feature can be used with YAML files, however there is no proper
pattern in `clap_app!` (yet).

Updates the derive example handling environment variables to illustrate
the case where it contains a sensitive value which should not be
displayed on the help screen.
Closes https://github.com/clap-rs/clap/issues/2101
Using `App::get_matches` from the integration tests meant that any
CLI arguments passed to libtest would also be captured by clap, often
causing the tests to fail.
For example, running `cargo test --test help -- --nocapture` would
result in several failed tests, even though `cargo test --test help`
worked fine. This was very surprising/confusing.
This commit makes the tests no longer implicitly rely on the value of
`env::args_os()`, which means developers can now provide arguments to
libtest without failures.
