Add proxy options for Axios calls

[jeremy-daley-kr]

For self-hosted runners where proxy is required, accepts an additional action input of proxy which is passed in as string to https-proxy-agent.

@daleyjem I may explore an approach more similar to your PR actions/configure-pages#63 rather than introducing customized input parameters for this Action. I'll try to get something in place in the next few days.

Thanks, @JamesMGreene . I started exploring the path of using the @actions/github package for this repo as well, but the API calls this one makes don't have certain things available... particularly the call to retrieve the artifact. The documented octokit.rest.actions.listWorkflowRunArtifacts() doesn't have data available until the workflow completes, whereas this line uses some "internal" API call where the data is immediately available after artifact upload:

const artifactExgUrl = `${this.runTimeUrl}_apis/pipelines/workflows/${this.workflowRun}/artifacts?api-version=6.0-preview`

I also can't find any documentation for the cancel/status endpoints, and the octokit.rest.repos.createPagesDeployment() isn't yet available in the latest @actions/github. Just too many factors of why I went this route instead.

@JamesMGreene Had another thought, if not wanting to use a proxy input, the action could obey the http_proxy/https_proxy (HTTP_PROXY/HTTPS_PROXY) env vars.

[JamesMGreene]

@daleyjem / @jeremy-daley-kr: All good points. 👍🏻

I'll look into this more today, as well as adding an issue to make sure we get those new API endpoints published to the REST docs now that they're more public (they're still technically "beta"... but a VERY heavily used beta 😊).

I'm thinking maybe it's time to switch from using axios to using @actions/http-client, which is the layer underneath @actions/github that provides all of the built-in proxy support for Actions things. 🤔

Opened alternative PR:

• Use the @actions/http-client and @actions/github modules for proxy support #124

Would be much obliged if you could assist with some real-world testing, @jeremy-daley-kr. 🙇🏻

Nice! I'll see if I can get a test going from your branch.
