Subject: [PATCH] Pin CacheControl to prevent missing dependency

schema-salad currently requires:
- "CacheControl >= 0.11.7, < 0.13"
- "lockfile >= 0.9", which is needed for CacheControl's FileCache until 0.12.11

but CacheControl 0.12.12 replaced lockfile with filelock.

Prevent the following traceback:

```
self = <cachecontrol.caches.file_cache.FileCache object at 0x7fe36ac5d190>
directory = PosixPath('/tmp/.cache/salad'), forever = False, filemode = 384
dirmode = 448, lock_class = None

    def __init__(
        self,
        directory,
        forever=False,
        filemode=0o0600,
        dirmode=0o0700,
        lock_class=None,
    ):

        try:
            if lock_class is None:
>               from filelock import FileLock
E               ModuleNotFoundError: No module named 'filelock'

/tmp/gxpkgtestenvcy0lxY/lib/python3.7/site-packages/cachecontrol/caches/file_cache.py:74: ModuleNotFoundError
```
