Refactor condition resource to return more metadata

Refactor condition resource

This refactoring includes:

1. Merging the function Condition and ConditionFromSCM, over time I realized that it didn't make sense to have them separated
2. Condition stores its result execution in a struct which allows to gather more additional data for building a meaningful report at the end of a pipeline execution
3. Only use logrus.Infof to describe in one place a specific condition execution, and move everything else to warning, errorf, or debug

Now a condition can result in of the following case:

• Condition successfull
• Condition failing without no error
• Condition failing with an erro

If the condition is failing with no error, then the final result can be changed with the failwhen parameter

Test

You should run as many test as you could
