Review comment:
using NULL, MIN, MAX to define these constants is quite confusing if we do
not check the value.

>
> Add new handler for fault injection.
> 1) If handler 'fault-injection' is added in application property
> file(microservice.yaml) then fault-injection handler should include in
> handler chain.
> 2) When handler is called read the configuration and listen the configuration
> event related to fault inject. The sample configuration file is in next slide.
> 3) The configuration mainly consist
> -delay
> -abort
> *delay:*can set the delay for requests based on percentage configured. The
> unit is ms. The delay percentage default value is 100%
> *abort*: Abort the requests based on percentage configured. For rest
> transport protocol error code can be configurable(500, 421) and highway
> protocol does not support for error return. The abort percentage default
> value is 100%
> 4) This features currently supports at consumer side.
