feat: Support trigger a recommendation manually

[qmhu]

What type of PR is this?

Feature

What this PR does / why we need it:

Manually triggering a recommendation can be done through the following steps:

1. Obtain the runNumber from the recommendationRule.

2. Modify the run number annotation for the recommendation that should be triggered. The run number should be lower than the runNumber in the recommendationRule. For example, if recommendationRule.status.runNumber=6, then change the annotation value to 5.

3. The recommendationRule controller checks for updates every 10 seconds. Once it detects the modified run number, it triggers the recommendation flow and updates the recommendationRule.status and recommendation. The recommendation's runNumber is modified to match that of the recommendationRule. You can use this to know when the manual trigger is finished.

It seems that only a single recommendation can be manually executed. Is it necessary to support manual execution of the recommendationrule?

[qmhu]

Last implement has a limitation: if the recommendation rule controller is reconciling, the manual trigger will wait, this is unexpectable. So we use a trigger controller to watch the decrease event.

How to trigger a recommendationRule is trick work. We can't modify the spec, but recommendationRule controller only watch spec changes...

@whitebear009 PTAL

[whitebear009]

the error is not handled

[qmhu]

if get run number failed , we treat it as a empty number which by default is 0.
