Allow specifying features for the installed crates

[Razican]

Motivation

I currently use this line in my workflows:

cargo install --features postgres --no-default-features diesel_cli

This action currently doesn't allow specifying features (or removing default features) of a crate, and that would be nice.

Workflow example

on: [push]

name: build

jobs:
  check:
    name: Rust project
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: actions-rs/[email protected]
        with:
          crate: diesel_cli
          version: latest
          features: postgres
          default-features: false
      - run: diesel migration run

Additional context

If we want to also support cache for this, we would need to add cache for different feature matrices, which might prove difficult.
