Use both provide-deps.sh files in devcontainer:
 * provide-CI-deps.sh install the deps for CI
 * provide-dev-deps.sh install the remaining deps for the devcontainer

Before this update, provide-CI-deps.sh was a subset of provide-dev-deps.sh

To distinguish the differet provide-deps.sh in the same folder, one for the CI container, one for the devel container

Use name conventions in .devcontainer

From git224 to git236

All the file in assets used tu build the devcontainer are moved in library-script.

Modify the Dockerfile COPY directory

The yum install commands were copy-&-paste from the 3  original images.
Now all the repo are installed first; then, they are followed by all the other packages merged together in a single yum install command.

To create the image defined in this dockerfile, we've merged three differend images:
 * storm2/build/base
 * storm2/build/ngx-voms-build [issue-17]
 * storm2/ngx_http_voms_module/.devcontainer
Each image has this own 'yum install' command with the packages needed for that layer.

With this commit, all the packages are installed in a single layer to reduce the image dimension.
All the 'yum install' commands are grouped in the setup.sh script.

The script can be used both for the devcontainer and for the continuous
integration.
