VOL-4905 - Deploy new voltctl version.

makefile/consts.mk
------------------
  o Import current library contsants makefile for additional defines.

Makefile
makefiles/release/include.mk
makefiles/release/release-build.mk
----------------------------------
  o Use std set -euo pipefail, -u missing, fix undef vars as needed.
  o Modularize, relocate release-* target logic into a named makefile.
  o Minor clenaups helped docker volume mount for /app/release => localhost:{cwd}/release.
  o Replace GO_SH inlined quoting with macro $(quote-single).
    - Syntax did not play well with editor colorization.
    - Magic trailing command quote appended to line continuation were ugly problems.
    - todo: replace with $GO_SH $(call quoted,command-text-line-continuation)
