CacheControl has changed how you enable its FileCache

[adamnovak]

As noted in DataBiosphere/toil#4212, CacheControl now needs filelock instead of lockfile to make FileCache work, as of patch release 0.12.12. The errors it throws have changed from telling you to install lockfile to telling you to install filelock. But since the module being used is clearly an implementation detail they freely swap around in patch releases, the right answer is to depend on CacheControl[filecache], which is the extra that brings along what you need for the FileCache to work.

So this doesn't work anymore:

schema_salad/requirements.txt

Lines 7 to 8 in ad423c4

	CacheControl==0.12.11
	lockfile==0.12.2 # needed for CacheControl's FileCache

And neither do any of the old releases.

Actually I don't understand why Toil is running into this given the pin on CacheControl's patch revision.

Oh, OK, here's what's being used to determine what to install when using schema-salad as a dependency:

schema_salad/setup.py

Lines 91 to 92 in 774157d

	"CacheControl >= 0.11.7, < 0.13",
	"lockfile >= 0.9", # needed for CacheControl's FileCache

That admits the 0.12.12 patch revision but doesn't accommodate its changed optional dependency.

Thanks @adamnovak for the report; looks like cachecontrol 0.12.12 got yanked, but I'll make a new release of schema-salad using the filecache extra which should avoid this in the future.
