Support for WebSite and Application smart alerts

[francisra75]

Hello, we are extensively using both Website and Application smart alerts.

We would like to know if you are planning to add support on this.

Application alerts are already covered with #74. However as this feature is still in beta I want to wait until it is stable.
For website monitoring I will consider this ticket as a feature request to support web site alert settings and will consider ti for a future release.

Thank you Florian, I will take a look. So then I should understand that those application alerts are what Instana considers calls "Smart Application Alert"?
I will test it to see how it works.

@francisra75 Smart Alerts is the terminology used in the UI. On API level they are call Website Alert Config (https://instana.github.io/openapi/#operation/createWebsiteAlertConfig) and Application Alert Config.

I'm currently completing implementation of #93 afterwards I would switch to this topic. If you provide a PR I will review and integrate it asap

Application smart alerts are now available with version 1.3.0 (instana_application_alert_config and instana_global_application_alert_config)

Website smart alerts are now also available with version 1.4.0 (instana_website_alert_config)
Closing the ticket as the requested features are now available.

@francisra75 please open new ticket when feature is incomplete or if you face issues with the current implementation
