installdriver: prompt on fresh install

[zhindes]

• This contribution adheres to CONTRIBUTING.md.

What does this Pull Request accomplish?

This adds a prompt for confirmation before kicking off a fresh install. Previously, we only prompted on upgrade. This has two benefits:

1. (Windows & Linux) Clarity on what is being installed
2. (Linux) A chance to opt out before we march forward interacting with the package manager

I also made a few minor cleanups

• removed unused variables
• include the cycle-based version in the prompts

Why should this Pull Request be merged?

Closes #623
