Support spackbot rebuilding all specs from source when asked (with "rebuild everything")
- Allow overriding --prune-dag cli opt with env var
- Use job variable to optionally prevent rebuild jobs early exit behavior
- ci rebuild: Use new install argument to insist deps are always installed from binary, but
package is only installed from source.
- gitlab: fix bug w/ untouched pruning
- ci rebuild: install from hash rather than json file
- When doing a "rebuild everything" pipeline, make sure that each install job only consumes
binary dependencies from the mirror being populated by the current pipeline. This avoids
using, e.g. binaries from develop, when rebuilding everything on a PR.
- When running a pipeline to rebuild everything, do not die because we generated a hash on
the broken specs list. Instead only warn in that case.
- bugfix: Replace broken no-args tty.die() with sys.exit(1)
