Witness update - Public nodes update

A quick update:

• Moved my public seed node (node.mahdiyari.info:2001) to USA for decentralization reasons

• Updated my public API node to the latest stack (https://rpc.mahdiyari.info) which now supports REST APIs

• Removed the old HafSQL public node (hafsql.mahdiyari.info). The details for the latest version of the public HAF/HafSQL database are available at https://mahdiyari.gitlab.io/hafsql

• Added full API stack to my haf docker compose stack (https://gitlab.com/mahdiyari/haf_dockers/) - Running this compose stack will give you a full API node the same as my public RPC API node. The difference between this and haf_api_node is in its simplicity. You can just clone and run.

• Soon will be adding Hivemind and HAF Block Explorer to the public HAF/HafSQL database.

• Added a page to monitor HBD health more accurately https://hivedex.io/hbd-health

For the past couple of months I have been busy with a Hive related project which will be announced soon. I'm able to work on Hive thanks to your continued support. Hopefully I can bring more value to Hive going forward.
