Do not add any labels to Docker images if addPipelineData is false

[Bemesko]

First of all, many thanks to @Parsa2820 for the PR on the original repository: microsoft/azure-pipelines-tasks#16604. All I'm doing here is making sure these changes can go ahead and be merged even after it was closed on the original repo.

Currently, even when setting both the addPipelineData and addBaseImageData to false in the Docker@2 task, the resulting docker command still includes 2 default labels:

--label com.azure.dev.image.system.teamfoundationcollectionuri=https://dev.azure.com/<my-org>/ 
--label com.azure.dev.image.build.sourceversion=<source version id>

When running the task inside a release it also includes the label release.releaseid.

This PR changes the behavior of the Docker@2 task so that adding labels with the values of system.teamfoundationcollectionuri and build.sourceversion can be enabled/disabled with the addPipelineData boolean variable, which can be set in the pipeline.

Task name: DockerV2

Description: Control the mentioned docker image labels. Previously these labels were always added, and there was no option to remove them. This behavior caused the private repository URI to be exposed in the docker image.
