New command, `spack change`, to change existing env specs (#31995)
If you have an environment like ``` $ cat spack.yaml spack: specs: [openmpi@4.1.0+cuda] ``` this PR provides a new command `spack change` that you can use to adjust environment specs from the command line: ``` $ spack change openmpi~cuda $ cat spack.yaml spack: specs: [openmpi@4.1.0~cuda] ``` in other words, this allows you to tweak the details of environment specs from the command line. Notes: * This is only allowed for environments that do not define matrices * This is possible but not anticipated to be needed immediately * If this were done, it should probably only be done for "named"/not-anonymous specs (i.e. we can change `openmpi+cuda` but not spec like `+cuda` or `@4.0.1~cuda`)
