Update the plugin to communicate with the staging server through HTTPS

[Jonas Raoni Soares da Silva]

Once the certificate gets setup in the staging server, ensure the plugin requests are under HTTPS by updating the base address to https://pkp-pn.lib.sfu.ca.

Note: The staging server cannot make use of auto-redirections from HTTP to HTTPS, as older plugin versions were making use of CURL, which won't follow redirections (plus, POST/PUT might get lost after the redirect).

The PRs cannot be merged yet, there's some underlying infrastructure work being done, so I've marked them as drafts.

The infrastructure work is done, the new domain is already pointing to the existing server, and the SSL certificate was issued.
I've also tested the plugin locally against it and the requests/responses worked fine.

@asmecher now these PRs can be merged:

[Alec Smecher]

Both merged, thanks! Can this issue be closed now or would you like to wait until after the server migration?

[Jonas Raoni Soares da Silva]

I've asked to keep both domains active and pointing to the same place, otherwise the old plugins won't be able to communicate with the staging server.
