Improve registration queries

[as51340]

Change registration queries to support config map syntax.
Example:

"REGISTER INSTANCE instance_1 WITH CONFIG {'bolt_server': '127.0.0.1:7688', 'management_server': '127.0.0.1:10011', 'replication_server': '127.0.0.1:10001'};",

"ADD COORDINATOR 1 WITH CONFIG {'bolt_server': '127.0.0.1:7690', 'coordinator_server': '127.0.0.1:10111'}",

[master < Task] PR

• Check, and update documentation if necessary
• Provide the full content or a guide for the final git message

To keep docs changelog up to date, one more thing to do:

• Write a release note here, including added/changed clauses
• Tag someone from docs team in the comments
