Add ability to put files and verify numFound for search
Add ability to put files and verify numFound for search

Specifying `{file_dir, Dir}` will create a list of all files in `Dir`
(non-recursive) and PUT them using the basename of the file as the
key.

Specifying the operation `{search, {Query, NumExpected}, P}` will run
a search with the specified `Query` and verify that the returned
`numFound` matches `NumExpected`.
