[chaudhari-priyanka]

Add job_title in the properties of TeamsChannelAccount interface Once this property will get added in the TeamsChannelAccount interface, we can get the return value for the same using TeamsInfo.get_member(TurnContext, String).

This requirement is required for multiple use cases, for example: we can decide the further bot flow on basis of the job title/designation of the end user.
