How would this feature be useful?

I have a similar problem as discussed in #1081 when attempting to pipx install a wheel on a machine without Internet access. All dependencies are available as wheels in a deps directory, and I pass --no-index and --find-links=deps options with --pip-args. Still, it is not possible to install the package, because pipx is trying to connect to the Internet without success, resulting in a connection timeout.

Having a global --skip-maintenance option would allow one to use pipx on machines without access to the Internet.

Describe the solution you'd like

I ported the fix provided in #1163 to the install command, so when calling pipx install --skip-maintenance, installing a local wheel works just fine.

In order to avoid code duplication, I suggest to make --skip-maintenance a global option to pipx, instead of implementing this feature for every single command it might be useful for, such that pipx --skip-maintenance install would be available.

Describe alternatives you've considered

The only alternative I have considered and tested so far is using pip instead of pipx (which successfully installs the wheel and dependencies, but without the isolation that comes with pipx).
