[PF-2348] Wrap command tokens with quotes

[iliadsh]

Previously, running a command like
terra gcloud compute ssh --zone us-central1-a jupyter@newenv --command "ps aux"
would fail to parse, as the space information in the quoted part would be lost when the command is built.

Do single quotes work?

If single quotes work, let's revert this PR

But double-quotes should work too. Though it doesn't make sense to me that these would be different? The flag parsing library should be providing the underlying value regardless?

Do single quotes work?

Just tested it with the ssh command and it doesn't appear to work. The dsub example doesn't work as expected either.

[melissachang]

Good point that double quotes should work, and that flag-parsing library (picocli) should handle this.

Is it possible to write a test that fails before this PR and passes after this PR?
