Description

While it is possible to get framework details and agent details from state.json or state-summary. There isn't an access point for getting master information.
It would very useful to have an access point that provides that information.

a collection of what is in zk would be fantastic.

example return:

{
	hostname: "10.0.6.183",
	cluster: "ken-v6ndoid",
	masters: [
		{"address":{"hostname":"10.0.6.183","ip":"10.0.6.183","port":5050},"hostname":"10.0.6.183","id":"832b06e2-5826-4823-8b6e-6df723865be6","ip":3070623754,"pid":"master@10.0.6.183:5050","port":5050,"version":"1.2.0"},
		{"address":{"hostname":"10.0.4.68","ip":"10.0.4.68","port":5050},"hostname":"10.0.4.68","id":"c5c03ffe-f37f-4503-b2b5-e7cf2c88c6b6","ip":1141112842,"pid":"master@10.0.4.68:5050","port":5050,"version":"1.2.0"},
		{"address":{"hostname":"10.0.5.52","ip":"10.0.5.52","port":5050},"hostname":"10.0.5.52","id":"032c3c33-32f5-4e61-b8d4-21c23275f18e","ip":872742922,"pid":"master@10.0.5.52:5050","port":5050,"version":"1.2.0"}
