[Akka-Scala] Add build.sbt to Akka-scala

[ramzimaalej]

PR checklist

• Read the contribution guidelines.
• Ran the shell script under ./bin/ to update Petstore sample so that CIs can verify the change. (For instance, only need to run ./bin/{LANG}-petstore.sh and ./bin/security/{LANG}-petstore.sh if updating the {LANG} (e.g. php, ruby, python, etc) code generator or {LANG} client's mustache templates). Windows batch files can be found in .\bin\windows\.

Description of the PR

This PR adds sbt build file to build generated clients by akka-scala.

@ramzimaalej thanks for the enhancement.

I did a test withsbt test but it reported the following errors:

[error] missing or invalid dependency detected while loading class file 'BasicMarshallers.class'.
[error] Could not access type NodeSeq in value scala.xml,
[error] because it (or its dependencies) are missing. Check your build definition for
[error] missing or conflicting dependencies. (Re-run with `-Ylog-classpath` to see the problematic classpath.)
[error] A full rebuild may help if 'BasicMarshallers.class' was compiled against an incompatible version of scala.xml.
[error] (NOTE: It looks like the scala-xml module is missing; try adding a dependency on "org.scala-lang.modules" : "scala-xml".
[error]        See http://docs.scala-lang.org/overviews/ for more information.)

But mvn clean test didn't report any issue so I'm not sure why...

@wing328 can you tell me which version of sbt and scala you used to test this. It works for me besides the warning

@wing328 I was not able to reproduce the issue. Could run the same command with this flag -Ylog-classpath

[wing328]

I'll add it to the CI to see if the CI reports similar issue.

CircleCI reports the same error: https://circleci.com/gh/swagger-api/swagger-codegen/2827:
