[FR] Add custom information to LogMonitor Events/Conditions

[Shabirmean]

Description

Currently it seems like we can define a default message for new conditions that are introduced.

"conditions": [
        {
                "type": "SomeNodeProblem",
                "reason": "NoProblem",
                "message": "some node problem not seen in the node"
        }
],

However, when rules are defined against this condition, we can only do a regex match for the logs and NPD will report the the matching log as is. In cases where we want to customize the message posted, there is no option to do this.

"rules": [
        {
                "type": "permanent",
                "condition": "SomeNodeProblem",
                "reason": "HaveProblem",
                "pattern": "failed: some node problem regex log"
        }
]

Is it possible to have an additional field to add to the matching log posted to by NPD? It can be a simple static message tha tis concatenated to the matching log message posted to NPD.

"rules": [
        {
                "type": "permanent",
                "condition": "SomeNodeProblem",
                "reason": "HaveProblem",
                "pattern": "failed: some node problem regex log",
                "message": "refer www.foo.com/docs for playbook on how to fix the issue"
        }
]

Type                Status    Reason                Message
------              ------    ------                ------
SomeNodeProblem     True.     HaveProblem.          failed: some node problem regex log; refer www.foo.com/docs for playbook on how to fix the issue

If this request makes sense I am happy to send a pull request to integrate it.
