Unified gateway image

[whynowy]

Is your feature request related to a problem? Please describe.
Different type of gateway has its own image, this is super hard to manage.

Describe the solution you'd like
Wonder if we can have a unified image with different args to start gateway deployment.

Look at following binary size information, please note gateway-server is the binary that I combined all the types to an unified one, its total size is around 78Mb, just 20Mb-30Mb larger than each of the individuals. I think this is something we should do. @VaibhavPage

Makes sense. The user will still have the ability to write a custom gateway server. So, I am fine with this change.
