Add support for notification types beyond email

[icco]

Is your feature request related to a problem? Please describe.

I would like to be able to channel the monitors generated by this to something besides email, such as Slack for warnings and OpsGenie for Criticals.

Describe the solution you'd like A clear and concise description of what you want to happen.

Being able to pass in an entire notification json blob for each level would be my preferred method.

Describe alternatives you've considered

We've thought about just importing the terraform used in this module.

As mentioned here sumologic supports for connection_type following options: Email, Webhook, PagerDuty,through Webhook supports several integrations (details here): AWSLambda, Azure, Datadog, HipChat, Jira, PagerDuty, Slack, Webhook, NewRelic, MicrosoftTeams, ServiceNow, and SumoCloudSOAR so we could consider adding support for other notification types

Yeah, the underlying terraform supports that, I just want support in the helm chart for it.
