regnat 58cdab64ac Store metadata about drv outputs realisations
For each known realisation, store:
- its output
- its output path

This comes with a set of needed changes:

- New `realisations` module declaring the types needed for describing
  these mappings
- New `Store::registerDrvOutput` method registering all the needed informations
  about a derivation output (also replaces `LocalStore::linkDeriverToPath`)
- new `Store::queryRealisation` method to retrieve the informations for a
  derivations

This introcudes some redundancy on the remote-store side between
`wopQueryDerivationOutputMap` and `wopQueryRealisation`.
However we might need to keep both (regardless of backwards compat)
because we sometimes need to get some infos for all the outputs of a
derivation (where `wopQueryDerivationOutputMap` is handy), but all the
stores can't implement it − because listing all the outputs of a
derivation isn't really possible for binary caches where the server
doesn't allow to list a directory.

regnat eb45308109 Fix the nix command with CA derivations
Prevents a crash because most `nix` subcommands assumed that derivations
know their output path, which isn't the case for CA derivations

regnat 8ad72b1f1c Properly test early cutoff with CA derivations
Build things with a different seed each time to make sure that it works
despite the different drvs

regnat ab21ab6501 Test the remote caching of non-ca-depending-on-ca derivations
Although the non-resolved derivation will never get a cache-hit (it
doesn't have an output path to query the cache for anyways), we might
get one on the resolved derivation.

John Ericson aad4abcc9c Fix floating CA tests
We will sometimes try to query the outputs of derivations we can't
resolve. That's fine; it just means we don't know what those outputs are
yet.
