Add algo stores to server from config

[bartvanb]

This PR makes sure that when config contains:

algorithm_stores:
  - name: Community store
    url: https://store.cotopaxi.vantage6.ai

That the community store will be available for all collaborations in that server

Looks very nice!
I put a few minor comments, and I have two highlights:

• I have just a doubt about the concept of having the server whitelisting themselves, because it sounds like bypassing the check of the store admin.
• I get now an error that I reported in the comments. I'm requesting the change just for this one (if it's not a mistake that I am making)

Works perfectly!

I added just a very last comment :)

I think that this should then be changed like this

Suggested change

	algo_store_url = algo_store_url.replace(
	"localhost", "host.docker.internal"
	).replace("127.0.0.1", "host.docker.internal")
	algo_store_url = algo_store_url.replace(
	"localhost", host_uri
	).replace("127.0.0.1", host_uri)

Ha thanks for spotting, that was a rather stupid mistake :-)
