Search before asking

• I had searched in the issues and found no similar feature requirement.

Description

The current alert content has some information like projectName, processName, logPath, I am consider can we add the task instance link to the content.
Then when job failed we can click the link directly into the instance, to check the log.

The link address pattern is like:

http://<uiAddress>/dolphinscheduler/ui/projects/<projectCode>/workflow/instances/<processId>?code=<processDefinitionCode>

• uiAddress
  need config when startup
• projectCode, processId, processDefinitionCode
  all can get them directly, because the current content has those fields.

Are you willing to submit a PR?

• Yes I am willing to submit a PR!

I think this is too bloated. We can provide some parameters and templates for users to edit the content of alarm information freely, just like grafana alarm.

It would be great if we can provide more freely way to customize the alert message.
