Show conditions in info object for transitions and rollover actions

[dbbaughe]

Currently we only show information like:
"Attempting to transition"
"Attempting to rollover"
"Rolled over index"
"Transitioning to "

This leads to these actions behaving like a black box in terms of what information they are acting on.
The default rollover API has to be called and will return the results of the evaluation (true/false) for each condition specified.

Suggesting we add something like below to the "info" map for each of these steps that are attempting to rollover or transition.

"info": {
    "message": "Attempting to rollover",
    "conditions": {
        "min_index_age": {
            "value": false
            "condition": "7d"
            "current": "6.35d"
        },
        "min_size": {
            "value": false
            "condition": "25gb"
            "current": "20.46gb"
        },
    }
}

This has been half completed.
The rollover conditions have been added as shown in linked issue that was merged.
The transition conditions still need to be added.
