api: Allow finding an asset by CID (of video or metadata)

[victorges]

What does this pull request do? Explain your changes. (required)

This is to allow finding an asset from its CID (of video or metadata).

It will allow clean-up of pins in any IPFS provider, so that we only actually delete
the Pin when there are no more assets pointing to that same file.

Will also allow unpinning of previous metadata when the NFT metadata changes,
following that same principle/api.

Specific updates (required)

• Allow indexes of nested properties
• Add index to CID fields
• Allow filtering by them on the /asset API

-

• How did you test each of these updates (required)
• yarn test
• to-do: Query for an asset using its CIDs and check it's findable

Does this pull request close any open issues?
Not really, but it's related to the current Piñata incident that we're having. Gotta create an issue for that.

• I have read the CONTRIBUTING document.
• My change requires a change to the documentation.
