Docker distribution for standalone service

Current MFT distribution is available as binaries and local installations require java to run that. We need to have a docker distribution of same binary and provide an option for users to select the mode they want to install MFT locally. Ideally the installation mode could be provided at the init command.

mft init --docker

This will greatly benefit non-java and windows users
