WC-1473: Add support for script content and script settings read/update endpoints

[echen67]

This PR is to support new endpoints that allow the user to read/update either only the script content or only the script settings of a worker, as opposed to currently having to always update everything together. This makes it easier on the user when they only need to deal with one aspect of their worker.

Has your change been tested?

I have added new tests to cover this change.

looks good in general, just a couple of notes from https://github.com/cloudflare/cloudflare-go/blob/master/docs/conventions.md#methods that we should update here for consistency.

[jacobbednarz]

thanks @echen67, this looks awesome. once we have those API schemas land, we're good to go here.

[jacobbednarz]

the API docs suggest this is just /accounts/:account_id/workers/scripts/:script/content. is that correct?

[echen67]

Ah, technically both work, but /v2 is preferred for this GET endpoint so I'll update the API docs to match. Thanks for catching this!

[jacobbednarz]

thanks for getting this one over the line @echen67 🚀
