So, for *CASE A*, check for filtering is as follows :
- the current line to be : *"{"*, and
- next line to be *""amInfo" : {"*
- And last line to be *"}"*
OR
for *CASE B*, check for filtering is as follows:
- the current line to be : *"{"*, and
- next line to be *"state" :*
- And next to next line to be *"}"* and line is the last one.
To figure out the start of JSON output.

> Example of expected response which can be JSON parsed:

> "desiredInstances" : 1,
> "liveInstances" : 0,
> "appStartTime" : 1466123287309
> }
> {code}
> The same output with MOTD message:
> {code}
> This is MOTD message
> This is MOTD message1
> {
> "amInfo" : {
> "appName" : "llap0",
> "appType" : "org-apache-slider",

> "desiredInstances" : 1,
> "liveInstances" : 0,
> "appStartTime" : 1466123287309
> }
> {code}
> Other scenario can be (eg: APP_NOTFOUND):
> *CASE B:*
> {code}
> This is MOTD message
> This is MOTD message1
> {
> "state" : "APP_NOT_FOUND"
> }
> {code}
> - We need to filter out extra lines initially added on top of JSON parseable
> string.
