Add `--no-install` option to only update files without installing

Feature Request

I want to add/remove a dependency and generate the lock file without installing. For example,

poetry remove --no-install requests
poetry add --no-install httpx

would update the pyproject.toml and poetry.lock but not install anything. Maybe someone can think of a better name than --no-install that would make sense for the remove case too.

poetry add --lock option already exists to handle this in 1.1.0b2. This can also be added into poetry remove command.

$ poetry@1.1.0b2 add --help | grep lockfile
  --lock                 Do not perform operations (only update the lockfile).

The goal is to prevent Poetry from installing or uninstalling anything, because that is slow and I don’t need it. I only want it to manage the pyproject.toml and poetry.lock files, not create a virtualenv or install anything.

Maybe it should be --dont-manage-environment and POETRY_DONT_MANAGE_ENVIRONMENT=1.
