Support for `pipx install -r requirements.txt`

Refinement from #357

Without digressing into defining “metapackages” having support for installing single environments from requirements.txt files would be very useful. For example, if we want to install a package that can allow for plugins at runtime (e.g. cookiecutter) we might want to additionally specify some plugin packages to install alongside it and we would write a requirements.txt file like so:

cookiecutter
jinja2_time

As discussed in #357 there is an issue with conflicting with previously installed packages. To solve this problem I propose some non-destructive default behavior and a way to override this in the CLI.

By default if you tried to install that file with pipx install -r requirements.txt pipx would try to install entry points for the first package in the list that defines them. If that package (in this example cookiecutter) already has entry points installed then it would fail by default:

> pipx install cookiecutter
> pipx install -r requirements.txt
'cookiecutter' is already installed, aborting installation.
Use the '--force' or '-f' command to force installation and replace current one.

If you want to override it you can pass the force option:

pipx install -f -r requirements.txt

Or you can specify an alias:

pipx install -r requirements.txt -a cookiecutter_ext

Thanks for your feedback. We can get pretty close to this behavior with existing APIs. What do you think of

pipx install cookiecutter
pipx runpip cookicutter install -r requirements.txt
