Update for a lot of Check to make their Sonar config up to implementation, update for rules.xml file (UT validation)

https://github.com/checkstyle/sonar-checkstyle/blob/master/sonar-checkstyle-plugin/src/main/resources/org/sonar/plugins/checkstyle/rules.xml

There is also https://github.com/checkstyle/sonar-checkstyle/blob/master/sonar-checkstyle-plugin/src/main/resources/org/sonar/l10n/checkstyle.properties with a lot of propetries info

one more registry of Checks:
https://github.com/checkstyle/sonar-checkstyle/blob/master/sonar-checkstyle-plugin/src/main/resources/org/sonar/l10n/checkstyle.propertiestchecks base on groups of Sonar.

registry of documentations for all Checks:
https://github.com/checkstyle/sonar-checkstyle/tree/master/sonar-checkstyle-plugin/src/main/resources/org/sonar/l10n/checkstyle/rules/checkstyle

in runtime we could load all checks and by reflection match all items in this xml

Attention:
validation is missed that problem - b5b3d1f

list of available tokens is still not validated, not violation after update to checkstyle 7.4 for NoWhitespaceAfter, WhitespaceAfter

Interesting project https://github.com/startupheroes/startupheroes-checkstyle/tree/master/startupheroes-sonar-file-generator-maven-plugin , unfortunately we can not use/copy their code but we can try to use them as binary

@romani We updated our license file (startupheroes-checkstyle) You can use our codes if you want. Good works.

checkstyle.propertiestchecks needs to be validated for tokens, as it contains a duplicate of acceptable and default tokens. It should also be validated for default value for other properties as they contain that too.

[rnveach]

from my previous comment. Sonar displays default values in a gray font below the property description if the rules.xml specifies something other than an empty string.
We probably shouldn't display the defaults in checkstyle.propertiestchecks if sonar will display the gray text for us.
You can see this for tokens in SuppressWarningsCheck and IllegalTokenTextCheck.

@romani As I am waiting for my current PR to be finalized, I am going to split this issue up into multiple so it is clear what needs to be done.

[rnveach]

Rules cardinality validation was added to Issue #87

[romani]

@rnveach , please close this issue is you split it completely.
Such huge issue is not good to keep.

[rnveach]

I believe I did split everything
