    Add SPDX license headers to python source files
    
This commit adds SPDX license headers to python source files as
recommended to
the project by the Linux Foundation. These headers provide a concise way
that is
both human and machine readable for communicating license information
for each
source file. It helps avoid any ambiguity about the license of the code
and can
    also be easily used by tools to help manage license compliance.
    
The Linux Foundation runs license scans against the codebase to help
ensure
    we are in compliance with the licenses of the code we use, including
dependencies. Having these headers in place helps that tool do its job.

It's very annoying when I forgot to add `-s` in `git commit` to
sign-off, because I then need to `git rebase HEAD~1 --signoff` and `git
push -f` to fix the DCO. This PR adds a hook to sign off commits
automatically when `-s` is missing to solve this problem. The only
change from the user side is now users have to install 2 hooks, so
instead of just

```
pre-commit install
```

Now we need to

```
pre-commit install --hook-type pre-commit --hook-type commit-msg
```

Note that even if users still only install the pre-commit hook, they
won't get any error in `git commit`. Just the sign-off hook won't run.
