Add device start-service and stop-service commands

Resolves: #2690

Please check the CONTRIBUTING.md file for relevant information and some
guidance. Keep in mind that the CLI is a cross-platform application that runs
on Windows, macOS and Linux. Tests will be automatically run by balena CI on
all three operating systems, but this will only help if you have added test
code that exercises the modified or added feature code.

Note that each commit message (currently only the first line) will be
automatically copied to the CHANGELOG.md file, so try writing it in a way
that describes the feature or fix for CLI users.

If there isn't a linked issue or if the linked issue doesn't quite match the
PR, please add a PR description to explain its purpose or the features that it
implements. Adding PR comments to blocks of code that aren't self explanatory
usually helps with the review process.

If the PR introduces security considerations or affects the development, build
or release process, please be sure to highlight this in the PR description.

Thank you very much for your contribution!

Hello @mlveggo and thanks for the contribution. Could you please git commit --amend your commit adding the Change-type footer so CI can run? This will look something like

Add device startservice and stopservice commands

Change-type: minor

Note that there is a blank line between the commit message and the footer. Thanks!

Great PR and feature addition, happy to have a community contribution! I've left some comments I would apply to both the start and stop service commands. My colleague will review as well when he has a chance

Hi, we would like to proceed with merging this PR, could you please rebase it and resolve the merge conflicts when you have a chance? Particularly we have updated our capitanodoc.js to update our docs (unfortunately we did not keep up with this well enough). You should just need to accept all of our changes and re-add your two new commands and re-run build

Seems an npm dedupe is needed to continue

Edit: To be clear, we will make a dedupe and rebase your PR when it's merged, no action needed on your part
