Dependant on #162

Green Squad encounter a significant number of duplicate tikets for known issues that could easily be cut down if people opted to check #platops-help or #cloud-native-announce prior to raising their ticket like the workflow asks them. Implement code to check #cloud-native-announce for them.

This code should look for posts in #cloud-native-announce that mention the team, environment or certain keywords also present in the ticket descriptor or brief and alert the user if any are found prior to submitting the ticket.
