SPI for automatic client/server registration/resolving (Moskito Inspect)

[bolbat]

Currently we have 2 options how moskito instances could be registered in servers list in standalone moskito inspect application:

• configuration (remotes in moskito-inspect.json)
• quick connect from ui
  Maybe we have more options, but i didn't made deep research.

And for big and dynamic production environments where everything is deployed frequently with containers with automatic scaling (based on load) this is not working approach (i'm about static configuration in moskito-inspect.json).

And we need some SPI for moskito (client role) when each application where moskito-core+rmi_api is integrated can register self in our "private registry" through own implementation.
And also we need some SPI for moskito (server role) (in our setup this is standalone moskito-inspect war application) through what we can resolve (from our "private registry") all running moskito instances.

For different projects/companies/environments for services registry can be used:

• etcd
• counsul
• apache zookeeper
• distributeme registry
• any custom solution (like in our case)

And moskito can provide some integration SPI (API) for all of this.

Default implementation (from the box) for this SPI's can use direct registration (with some keep-alive functionality) from moskito (client role) to moskito (server role) through just IP configuration.

I know that i can provide a pull request with such functionality, but i think for the first we should have a discussion about this feature.
