Remove Redundant Coins

[psavva]

Removed: HomeCoin, SerfNet, Solaris

The "chains" JSON files should not be removed. Anyone running indexers for those chains, will stop working.

Will keep SERF running a little while more, got a few connections on it.

[psavva]

@sondreb Do you want to keep all 3 chains files or just that of SERF?

I will undo SERF in totality, and keep it as it was prior to this PR.
I will continue to remove HomeCoin and Solaris

[sondreb]

Everything in the "chains" folder must be kept around for a long time. Can remove the docker setup for HOME and XLR, and also from the large .json files that is used to list in explorer. Thanks!

Hi @sondreb

Apologies for the delay in reverting back.
Chains.json has been restored to the version prior to this PR.

Please check if it's ok to merge :)

Done

HOME.json and XLR.json cannot be deleted. If they are deleted, all indexers running for those chains will crash and fail, if they don't run with custom settings.

To clarify: If anyone in the world happens to spin up a HOME indexer, the indexer software will retrieve the HOME.json for configuration settings. It doesn't have to be shown in the official list on our explorer though, but we must keep those configuration files around for a while.
