Specify --network with URL such as testnet.polykey.com

[tegefaulkes]

Specification

Currently the network option takes either mainnet or testnet, these are hard-coded into the config file and resolved to the URLs mainnet.polykey.com and testnet.polykey.com respectively.

We should change this to use the mainnet.polykey.com or testnet.polykey.com directly. So when selecting the network option when starting polykey it's either specified with the option as ---network mainnet.polykey.com with the default as mainnet.poykey.com. The ENV variable will likewise be the same PK_NETWORK=mainnet.polykey.com`.

This will slightly reduce the complexity while allowing any properly set up network URL to be used.

Tasks

1. Remove network names and information from the Polykey config.js.
2. Update the CLI option to take and parse hostnames.
3. Update the CLI option to default to mainnet.polykey.com.
4. Update any tests that depend on this change.
5. Update any CI jobs that depend on this change.

This is already done right? Didn't @amydevs fix this a while back?

[CMCDragonkai]

Can you verify?

[tegefaulkes]

Nope, not actually done yet. The CLI option still needs to be modified to take the URL rather than the network name.

I've made the change on staging, I now need to make the change in Orchestrator as well. Otherwise the deployment of seednodes will be set to the wrong hostname

[CMCDragonkai]

So CLI PR and Orchestrator PR then? Need to reopen.

[CMCDragonkai]

Oh is the Polykey-CLI done here then? 3525826.

Orchestartor PR could be done separately - but should be kept track here.

This has already been done in Orchestrator, I just pushed a commit because it was a 1 line change:
