Feature: Group/Rule-wise Configuration of Warning/Failure Thresholds

[SebastianWendorf]

Currently it is possible to define a general severity at which a warning/failure during the jQA analysis should occur. This is done via the jqassistant.analyze.report.warn-on-severity and .fail-on-severity configuration properties, where a concrete severity value like MAJOR can be set.

To allow more fine-tuned configuration possibilities it would be good to override the general thresholds described above with group/rule-wise thresholds.

In addition to the current configuration mode, it should be possible to define the warn-on-severity and fail-on-severity as YAML mappings with the "*" key to set the default value and concrete rule/group names as keys for partial overrides of the default value. The use of wildcards should be allowed for the description of rule names.

Example:

jqassistant:
  # ...
  analyze:
    report:
      warn-on-severity:
        "*": MAJOR
        "my-important-group": MINOR
        "spring:*": CRITICAL
      fail-on-severity:
        "*": CRITICAL
        "my-important-group": MAJOR
        "spring:*": BLOCKER
