v1.1.2 Release

[dcheckoway]

Several small branches will get merged to this branch, which represents the RC for v1.1.2. The foundation of this branch is dependency upgrades made via:

• go get -u github.com/grafana/grafana-plugin-sdk-go
• npx -y @grafana/create-plugin@latest update

NOTE: You'll see some webpack stuff in the diff, that's just part of the dependency upgrades.

I've verified the changes:

• query timeouts are working
• queries are cancelled on the Cribl end when the timeout is reached
• improved error messaging
• usage of variables for saved query types works
