Add topicprefix to /api/server/info #292

Closed stuarteberg closed 5 years ago

stuarteberg commented 5 years ago

As a result of 97f70bc28999617dfefd23b8192b4cc0fc77d4b5 and 1b5f82e83f47788b0e56c49d0290d001caf8e8d1, the formula for choosing kafka topic names now depends on a field from the TOML file: topicprefix. Therefore, clients who wish to read kafka logs need a way to obtain the topicprefix from DVID.

As far as I can tell, /api/server/info does not list the topicprefix. Can you expose it?

Alternatively, it might be a bad idea to simply provide access to the entire TOML file via a new endpoint like /api/server/toml or something like that.

There is now a field "Kafka Activity Topic" that will be empty string if not set or the string. Just like "Kafka Servers" these fields will only show up if kafka servers are configured.
