start of work to test automated builds with build cache

I will likely update this PR many times until I can get it working.

+This is a testing repository for ideas to:
+
+1. Perform automated builds at some frequency to ensure flux packages build with spack
+2. To keep a build cache that can make this more speedy.
+3. To have a process for updating versions on new releases (via some other trigger)
+4. To keep package recipes here, and automatically update upstream spack

+Subject: [PATCH 1/1] build: fix build errors with side-installed 0MQ
+
+Problem: when building against side-installed libzmq, libczmq,
+compilation fails with a missing zframe_t definition.
+
+If the side installed 0MQ packages were built with the "draft APIs"
+enabled (the default), libczmqcontainers/zhashx.h and zlistx.h define
+function prototypes using zframe_t.  Extend CZMQ_BUILD_EXTRA to
+include those prototypes so they are never defined in libczmqcontainers.
