Addition of new release and tag workflow files

[adrianZahra]

Aim: To separate the release of the SPS Frontend from the SPS Framework by adding the ability to tag and release container images of the frontend and to push the frontend npm package all from the frontend repo sepera.

What was added:

1. tag-workflow.yaml: the github workflow for building container images upon taging
2. release-workflow.yaml: the github workflow for building and pushing the frontend to NPM when making a github release.
3. build-images-core.sh: the script that gets our cloud provider and version and builds and pushes our docker container
4. http-server.dockerfile: the script that gets executed in build-images-core to build our docker container from our npm taged repo

Purpose: The aim of this merge is to merge in the new tag and release workflow files as well as the new sps-frontend docker file. These files will be responsible for carrying out the new release method for the sps frontend.

How to use Tag-Workflow:

1. bump the version of the sps library
2. commit the version bump
3. tag the version git tag v1.0.1dev
4. commit and push the tag git push && git push origin v1.0.1dev
5. head to the Actions tab for the SPS Frontend repo to view the workflow https://github.com/ScalablePixelStreaming/Frontend/actions
   The workflow will create an sps-frontend docker image for useage in the tensorworks/sps-frontend repo

How to use the Release-Workflow:

1. after running the Tag-Workflow successfully head to https://github.com/ScalablePixelStreaming/Frontend/releases/new to create a new release based on the new tag
2. publish the new release
3. view the workflow at https://github.com/ScalablePixelStreaming/Frontend/actions
   The workflow will create a new npm package for users to consume
