Adds: * Modern flake8 settings for per-path/glob error ignores, allows packages to use the same `.flake8` as the rest of spack * A spack formatter plugin to flake8 that implements the behavior of `spack flake8` for direct invocations. Makes integration with developer tooling nicer, linting with flake8 reports only errors that `spack flake8` would report. Using pyls and pyls-flake8, or any other non-format-dependent flake8 integration, now works with spack's rules.
To get working completion of directives and spack components it's necessary to import the contents of spack.pkgkit. At the moment doing this makes flake8 displeased. For now, allow spack.pkgkit and spack both, next step is to ban spack * and require spack.pkgkit *.

Absolutely. I actually started to do it but decided to put this up this way first in case we wanted to preserve that for some reason. The only reason I can think of we would want to do that is that the plugin system is relatively newish to flake8, but since CI runs a new version, and it's only a pip install away I'm not sure that matters so much. I can refactor the command on top of this shortly. As to the placement, I put it there just to keep it with the qa stuff, but we can pretty easily move it elsewhere. |

How new is newish? Regardless, I'm still in favor of it for the same reasons you outlined. The only potential problem/annoyance is if we introduce a change that means |

Support for this kind of local, uninstalled, plugin was added in 3.5.0 which was apparently released in October of 2017. How do the spack flake8 tests currently work, since flake8 doesn't support python 2.6? |

Rebased. |
It looks like we use a |

Cool, it claims to so I'll put together that refactor and see what the CI thinks of it. |
This version still copies all of the files to be checked as befire, and some other things that probably aren't necessary, but it relies on the spack formatter plugin to implement the ignore logic.

That was a little nastier than I thought because of |
I ran into this in the PR converting pkgkit to std. The solution in that branch does not work in all cases as it turns out, and all the workarounds I tried to use generated configs to get a single invocation of flake8 with a filename optoion to work failed. It's an astonishingly frustrating config option. Regardless, this removes all temporary file creation from the command and relies on the plugin instead. To work around the huge number of files in spack and still allow the command to control what gets checked, it scans files in batches of 100. This is a completely arbitrary number but was chosen to be safely under common line-length limits. One side-effect of this is that every 100 files the command will produce output, rather than only at the end, which doesn't seem like a terrible thing.
Apparently zip_longest didn't exist in python 2.7, nor did commas at the end of argument lists.

This PR does three related things to try to improve developer tooling quality of life: 1. Adds new options to `.flake8` so it applies the rules of both `.flake8` and `.flake_package` based on paths in the repository. 2. Adds a re-factoring of the `spack flake8` logic into a flake8 plugin so using flake8 directly, or through editor or language server integration, only reports errors that `spack flake8` would. 3. Allows star import of `spack.pkgkit` in packages, since this is now the thing that needs to be imported for completion to work correctly in package files, it's nice to be able to do that. I'm sorely tempted to sed over the whole repository and put `from spack.pkgkit import *` in every package, but at least being allowed to do it on a per-package basis helps.
