More docker build options via the configuration

Is this a BUG REPORT or FEATURE REQUEST?: feature request

Description

Looking at the usage docs, there are a few items than can be configured:

buildArgs
build.squash
etc.

However docker's build command has many more options. I think it would be great to be able to config all of them as well.

How to reproduce

For example: using the command line it is possible to do

docker build . -t myimage --add-host myhost:172.123.123.123

There is no way to do the equivalent using this plugin (yet).

Apart from --add-host, there are also other options available in the CLI.

What do you expect

Something like this to be possible in the plugin configuration in the pom file:

(...)
            <configuration>
              <repository>myimage</repository>
              <addHosts> <!-- this is my suggested addition -->
                <myhost>172.123.123.123</myhost>
              </addHosts>
              <!-- other options like `rm` etc -->
            </configuration>
(...)
