Gud Boi 119d2c0495 Declare per-daemon-kind backend mod groups 
Prep for the `brokerd` -> (`datad` + `brokerd`) actor split
by having each (split-style) backend declare which of its
submods host which daemon-kind's eps, exactly per the
`piker.data.validate._eps` groupings; `ib` already had
`_brokerd_mods`/`_datad_mods` so extend the convention to
`kraken`, `binance` and `deribit` (and add `'api'` to ib's
datad set since both kinds need the `Client` layer).

`__enable_modules__` stays as the (deduped) union so this
is a ZERO behavior change; flat backends (`kucoin` etc.)
just don't declare the split yet.

Also,
- add `validate.get_eps()` returning a backend's defined
  eps per daemon-kind for spawn-time introspection.
- import `NoBsWs`/`open_autorecon_ws` from
  `piker.data._web_bs` directly in `.kraken.broker` (they
  were only re-exported via `.kraken.feed`) so the trading
  mod doesn't depend on the feed mod for ws primitives.

kraken backend

though they don't have the most liquidity of all the cexes they sure are accommodating to those of us who appreciate a little xmr.

status

current support is production grade and both real-time data and order management should be correct and fast. this backend is used by core devs for live trading.

config

In order to get order mode support your brokers.toml needs to have something like the following:

[kraken]
accounts.spot = 'spot'
key_descr = "spot"
api_key = "69696969696969696696969696969696969696969696969696969696"
secret = "BOOBSBOOBSBOOBSBOOBSBOOBSSMBZ69696969696969669969696969696"

If everything works correctly you should see any current positions loaded in the pps pane on chart load and you should also be able to check your trade records in the file:

<pikerk_conf_dir>/ledgers/trades_kraken_spot.toml

An example ledger file will have entries written verbatim from the trade events schema:

[TFJBKK-SMBZS-VJ4UWS]
ordertxid = "SMBZSA-7CNQU-3HWLNJ"
postxid = "SMBZSE-M7IF5-CFI7LT"
pair = "XXMRZEUR"
time = 1655691993.4133966
type = "buy"
ordertype = "limit"
price = "103.97000000"
cost = "499.99999977"
fee = "0.80000000"
vol = "4.80907954"
margin = "0.00000000"
misc = ""

your pps.toml file will have position entries like,

[kraken.spot."xmreur.kraken"]
size = 4.80907954
ppu = 103.97000000
bs_mktid = "XXMRZEUR"
clears = [
 { tid = "TFJBKK-SMBZS-VJ4UWS", cost = 0.8, price = 103.97, size = 4.80907954, dt = "2022-05-20T02:26:33.413397+00:00" },
]
