Adding Version Endpoints to all apis

[hattan]

Purpose

This PR introduces new endpoints for all apis. The endpoint is /api/version/

This is done via a docker environment variable that is assigned during the docker build phase. This can be set via the command line by adding --build-arg to docker build.

The purpose of this is to make it easy and provide a standard way for teams to see updates to their api. Rather than having to mess with the code for each api (and change healthchecks) , teams can easily add --build-arg to their pipeline.

For example:

docker build -t api-poi:$(Build.BuildId) --build-arg build_version=$(BuildBuildId)

By doing this during an automated build the deployed api will always show a unique version number in it's version endpoint. This makes it much easier for folks to see changes without needing to update the api code itself.

Does this introduce a breaking change?

[ ] Yes
[X] No
