Support watching keys and services directory

[avthart]

With Consul and other solutions like etcd, it is possible to watch for changes within services and keys directories. The current Spring Cloud API does not support this kind of functionality. Are there any plans to support this?

"Watches are a way of specifying a view of data (e.g. list of nodes, KV pairs, health checks) which is monitored for updates. "

Yep, it will be great functionality, cause in real life, when I use docker with consul, I use consul template for real time change system configs. For example nginx conf.

So I implemented a watch here 8ffa7e0. I didn't implement watches in any kind of generic sense. Wondering what that would look like. Here, it's specific to the ConsulClient api.

Great! Will have a look at it.
