[JENKINS-68187] writeFile : Add the possibility to add content

Currently when calling writeFile on an existing file, the content to write overwrites the existing content.

A boolean parameter (append ?) could be used to tell writeFile to add rather than erase. E.g.

writeFile(

     file:myLog.txt,

     text:'An additional information',

     append: true

)
