Basic Docker support

Basic docker support is to provide the following Docker features:

• pull/add images from registry
• list images
• list containers
• start containers from an image
• stop/restart/kill containers
• connect/disconnect from containers to show log/provide interactive console/terminal
• build dockerfile (available via right click on DockerFile / project / file with DockerFile - this should support .dockerignore)
• filter image/containers
• provide details for image/containers
• during launch be able to mount volumes, port forwards etc. in a simple UI (leave more advanced details to separate pages/different ui)
• provide API for other tooling in eclipse to use it (like server launches etc.)
