[hailctl] make the output of dry-run copy-pasteable (hail-is#14127)

Here's a diff of `hailctl dataproc start foo --dry-run` on main and on
this branch. Notice that the properties and metadata arguments gain a
leading and trailing single quote. This ensure that things like
`sys_platform!="win32"` are properly transmitted.

In `start.py` we just use exec-style invocation, so there's no
equivalent issue.
