AppInsights migration - Removing duplicated key
On MR !720 (merged) we introduced new appinsights migration approach, however, missed following from docs:
Important Don't use both a connection string and an instrumentation key. The latter one set supersedes the other, and could result in telemetry not appearing on the portal. See missing data.
SLB engineers are concerned about this statement, therefore, removing key will alleviate these concerns.
