FrostFS Rebranding

[alexvanin]

• Update gateway images
• Update gateway configuration
• Update core images
• Update core configuration
• Update networks in docker-compose
• Update README
• Update docs
• Update Makefile and all related .mk files

Follow-up step one:

• Use locode from https://github.com/TrueCloudLab/frostfs-locode-db
• Remove main chain component (requires legacy contract deploy routine, so we cut it)
• Remove coredns dependency (it is not required by environment)

Follow-up step two:

• Return main chain component with full Adm tool integration
• Return coredns with new integration
