Kontena 0.5.0 Released

Howdy! While celebrating 1st of May, we have been also working on Kontena 0.5.0 Release. This release contains number of bug fixes and code changes needed for our upcoming releases. With this release, we were able to fix Docker's streaming API memory leak problem causing kontena-agent nodes to run out of memory after a while. In essence, this is a problem of Docker itself, but we found a way around it. See below for full list of changes:
