Not suggest terrascan

[yu-iskw]

terrascan is no longer actively maintained. So, it would be good not to suggest even if related files exist.

Hi @yu-iskw! Thanks for flagging this: I'll discuss with the team if we want to go ahead and turn this off by default for everyone. A couple questions:

• What made you say it's no longer maintained? It looks like their last release was in March (although I do see the substantial backlog of issues)
• Were you encountering a lot of linter failures when running terrascan in your repo? If so, could you include the failure outputs? It's possible we can modify our integration to improve the failure rate.

According to the commit stats of terrascan, I don't think it is actively developed.

For instance, terrascan doesn't support newer versions of terraform. For instance, it doesn't support the import block. I encountered violations caused by the less active maintenance. So, I decided not to use terrascan.

I talked this one over with the team, and we agreed to disable it for now. Thanks for the PR!
