feat(jans-lock): dashborad with network details and instances statistics

[yurem]

We need to add new panels to AdminUI to show details about Lock network topology, load, statistics, etc

Lock is lightweight application which works as proxy between other Jans applications and OPA. In generic deployment the number of nodes might be even greater than count of jans-auth instances. Also Lock might work with limited permissions to access DB tables to get only required data. All these conditions force to move statistic gathering part to another service which has less active nodes.

In proposed flow each Lock instance can request statistic from OPA and forward it to specific channel to PubSub server.
In order model the best candidate which can receive these messages is config-api. After getting message it can process it and store in DB to allow AdminUI to request it.

Here is list of issues needed to resolve close this task:

1. feat(jans-lock): each Lock instance should send statistic periodically to specifc PubSub channel #8386
2. feat(jans-config-api): add plugin to config-api to subscribe for messages #8387
3. feat(jans-config-api): config-api should parse and store data in easy for requests execution format in DB #8388
4. feat(admiUI): adminUi should request data from config-api to display for administrator #8390
5. feat(jans-config-api): config-api should provide endpoints to access stats from DB #8389
