Massimiliano Culpo c291866b9a build env: simplify handling of parallel jobs (#11524) ... This PR implements several refactors requested in #11373, specifically: - Config scopes are used to handle builtin defaults, command line overrides and package overrides (`parallel=False`) - `Package.make_jobs` attribute has been removed; `make_jobs` remains as a module-scope variable in the build environment. - The use of the argument `-j` has been rationalized across commands - move '-j'/'--jobs' argument into `spack.cmd.common.arguments` - Add unit tests to check that setting parallel jobs works as expected - add new test to ensure that build job setting is isolated to each build - Fix packages that used `Package.make_jobs` (i.e. `bazel`)		2019-05-24 11:45:22 -07:00
