Container Image Builds.

Closes #65.

It's just occurred to me that we still need the observability address set in cases that an observability endpoint is present, this is indicated by the observability address being a command line option.

In the case they are, the observability address environment variable should be set.

In the case they are not, the observability address variable is not required, nor in the ExposedPorts.

The last thing to do is to remove any left over Containerfiles and .containerignore.

@Henry-Denny Looks like there are conflicts that need fixed here.
