chore(devops): Import setup command (#3864)

# Motivation
The setup command is a general purpose command for installing command
line tools.

# Changes
- Copy the `scripts/setup` from the chain-fusion-signer codebase.
- Use the `.sh` suffix to adhere to Oisy policy.

# Tests
The tool is exercised extensively elsewhere. The only adjustments are
formatting and naming to match local policies.

scripts/setup.sh
