build persistent environment for CI

[bam241]

We should try at least for ubuntu/linux to build persistant docker environment to build the plugin, instead of rebuilding it every time....

We can do this with GH actions! Maybe @shimwell can lead this effort?

Dynamic building is nice as it uses the latest dependencies, while using a persistent docker environment is nice as it gets through the tasks quickly.

Perhaps caching is the way to go here as it allows the best of both

I can certainly have a go with this

this is redondant with #118

Now that we switched to docker for our linux build, we should pre-build the docker image with all the pre-requisites in it.
