Change rule keys containing non standard characters

[jenspopp]

Due to a stupid question there is now a ticket to change rule key validation:

https://sonarsource.atlassian.net/browse/SONAR-21052

This affects all keys that have any character not in regex ^[\w]+$ which is [a-zA-Z0-9_]. This means, any key of e.g. the gcc compiler plugin will need to be changed to match this regex (e.g., replace - with _)

Others need to be checked...

The changes will need to mainly be in the rule definition / creation and in the scanner sending the issues. Any non matching character needs to be replaced before use in sonar.
