{cmd/storagenode,Makefile}: add storagenode base image Dockerfile

Having the storagenode and storagenode-updater processes in one container
requires a process manager to properly handle the individual processes.

Using a process manager like supervisord requires that you package
supervisord and it configuration in the image, along with the storagenode
and storagenode-updater binaries.

Installing supervisord requires that we run apk to install it and its
dependencies at build time which makes it difficult to build multi-platoform
images; executing apk forces a requirement of the build system to run
foreign architechtures.

This change adds a dockerfile which will be used to build the base image
for the storagenode and has supervisord packaged. The base image will be
built manually using docker buildx, with QEMU binfmt support.
