Check DVC releases to update containers

[iesahin]

The container upgrade currently uses --no-cache option of docker build to update DVC versions. Although most of the layers are common across containers, they are not reused, in order to upgrade the DVC version.

We need a better way to handle DVC version dependency. For example, build-all.zsh script can use the output of curl -s https://api.github.com/repos/iterative/dvc/releases/latest command to check if there is a new version and use this as a --build-arg. That way we can be sure that the intact layers are reused, both from previous ones and the current one, and DVC version is upgraded when necessary.
