Create Cadence 1.0 pre-release installer

[jribbink]

Closes #1374

Description

Creates a Cadence 1.0 pre-release installer. This installer will iterate through all of the Flow CLI releases (99.99999% will be on first page anyways) and install the latest release containing cadence-v1.0.0.

• We should update C1.0 install instructions to run the install script from stable-cadence branch instead of master
• We should make sure that all C1.0 releases are tagged with vX.X.X-cadence-v1.0.0.X
• We should make sure that we do not merge these changes into master as they are C1-specific and temporary

@jribbink what about uninstalling? Should we add support for that too?

@jribbink what about uninstalling? Should we add support for that too?

I think this is probably a separate ticket. It's not blocking to get this functionality out & we don't even provide a mechanism (outside of homebrew) to do this with our existing install script. It's probably a question of providing an uninstall.sh/uninstall.ps1 script IMO.

code looks fine, lets give it a shot
