Support node type or node tags as condition in MongoDB Atlas Alert
Currently, the MongoDB Atlas does not support the node types  or node tags  as the condition in Atlas alerts. That would be super inconvenient for the following scenarios.
Scenario 1: If the user wants to create an alert to monitor the specific node type, such as READ_ONLY node or ANALYTICS nodes, there is no convenient way to achieve it. The current approach must set up the alert by using the hardcode hostname.
Scenario 2: If the user has some electable nodes and a analytics node in a cluster, and wants to focus on monitoring the electable nodes (workload), they can not directly exclude the analytics node from the alert. The current possible approach is to exclude the hostname of analytics nodes in an alert. If the user adds more analytics nodes, they must edit the alert again.
We believe that having these features in Mongo DB Atlas can increase the flexibility for a user to set up the alert to monitor the metrics in the above scenarios.
