Change the switch/case indentation sourcecheck policy

Since recently I have been playing with our sourcheck to hook it in as a GitHub action at each PR, I have been fixing some sourcecheck findings leftover from previous unchecked commits.

Most of the stuff makes sense but this one:

// Some comments here
        <module name="Indentation">
            <property name="lineWrappingIndentation" value="0"/>
            <property name="caseIndent" value="0"/>
        </module>

this impose that switch/case blocks should be in the form of:

switch(...) {
case:
    ...
case:
    ...
case:
    ...
default:
}

i.e. switch and case keywords MUST have the same indentation. I have searched a little bit and it seems this is not widely used as a code style, the tendency is to have the case indented.

Since there are 2053 occurrences of switch/case blocks, before attempting to fix this I would like a general agreement on this.
