Adding annotations for deployment to values

[MatthiasWerning]

It would be very great to have annotations for the deployment itself. As there is currently no way to do that, we would have to clone and integrate the entire chart into our parent chart which is a mess just to change a few lines there.

For example the wave project for kubernetes requires a certain annotation on deployments / statefulsets in order to be active.
As there are annotations available for almost all other resources that would be a great minor addition which would help a lot!
