Use a cache mount to speed up rebuilding compute node image (#10737)

Browse Source 
Building the compute rust binaries from scratch is pretty slow, it takes
between 4-15 minutes on my laptop, depending on which compiler flags and
other tricks I use. A cache mount allows caching the dependencies and
incremental builds, which speeds up rebuilding significantly when you
only makes a small change in a source file.
