Consul watches support for Micronaut Service Discovery

Currently supported watches by Consul [1]:

• key - Watch a specific KV pair
• keyprefix - Watch a prefix in the KV store
• services - Watch the list of available services
• nodes - Watch the list of nodes
• service- Watch the instances of a service
• checks - Watch the value of health checks
• event - Watch for custom user events

Cloud Object Storage Abstraction Layer

Q: Shouldn't we name it like Cloud Agnostic Object Storage Interface

The Object Storage is one of the fundamental services provided by the cloud provides. The objects are generally stored in the tree directory structure similary like on the file system. The objects are consumed either by API or in most cases by their unique HTTP URL or by cloud specific internal URI (See Appendix 1).

Motivation

The initiative addresses a growing need to support the hybrid cloud applications by allowing the developers to transparently access and manipulate the objects from within applications running in various cloud environments.
