[JENKINS-33173] Improve how to get output of sh execution

Usually when you execute some shell script and you need to reuse the output for another shell script or internal you need to do something like:

sh('git rev-parse HEAD > GIT_COMMIT')
git_commit=readFile('GIT_COMMIT')

This is ok, but maybe we could provide something like:

git_commit = sho('git rev-parse HEAD')

sho = shell output
which basically takes the output and put it in a var.

Another option could be adding a parameter to sh that indicates that we want to capture the outout and return it back.
