Allow filter of list endpoint

[tcezard]

The list endpoint should allow for filter to be applied to limit the amount of sequence collection returned.
In first instance we should allow filtering by level1 digests of specific properties. For example:

list?sequences=hsobfd02h2cjta923flhyfsx

Should only return sequence collection level 0 digest that contains a set of sequence which level1 digest is hsobfd02h2cjta923flhyfsx

This should be applicable to all properties that have level 1 digest.
In our case that would be sequences, names, lengths, md5_sequences, and sorted_name_length_pairs
