Add support for MemorySwappiness

[maxant]

Fix #1546

[rohanKanojia]

@maxant : Thanks for the PR, Could you please address test failures?

[maxant]

@rohanKanojia sorry for the wait :-)

Can I add a couple other properties into this PR or should I create a new issue? It would be more of the same for Init and MemoryReservation

@rohanKanojia on the e2e tests I get this error:

https://app.circleci.com/pipelines/github/fabric8io/docker-maven-plugin/447/workflows/c5ab7a02-823e-4278-b401-dd8513241f29/jobs/4232?invite=true#step-103-1342

I don't really understand the error message - do you have any tips?

Umm, not sure about e2e failures. Could you please try rebasing your branch and see if it gets resolved?
