feat: add --wait/--no-wait flags to certain cli commands (#2378)

This PR solves issue #2359.

It adds a new `--wait` flag (default `true`) to control whether the cli
waits for transactions to be mined. It also adds the equivalent
`--no-wait` flag to disable this behaviour and have the cli return early
with the transaction hash. These flags do not have short-hand variants.
