feat(price-feeder): Convert remaining providers to the Websocket Controller

[zarazan]

Description

Converted the remaining providers over to use the Websocket Controller. For each provider I cross referenced the current API docs with how we currently handle their websocket and tuned it to maintain a stable connection.

Changes other than just converting providers to use the Controller:

• Coinbase: Added a ping loop to keep the connection alive longer
• Crypto.com: Changed the pricing info to parse into strings instead of float to correctly read prices
• Huobi: Add the HuobiSubscriptionResp to handle subscription response messages and prevent an erroneous error
• Added a second context to the WebsocketController to kill the old ping loop after a reconnect happens. Otherwise we risk running multiple ping loops for a single provider.
• Added an integration test that tests creating an active connection, receiving and parsing prices for each provider websocket we have implemented.

closes: #1507

woo! Checking this out @zarazan

[adamewozniak]

looks good! just need tests to pass.

would like another review, maybe from @rbajollari / @RafilxTenfen before we merge this in

[adamewozniak]

oh, and changelog please!

[RafilxTenfen]

With this implementation, peggo cannot update the price-feeder version anymore, basically peggo does not know which prices will have to query when instantiating new providers. The new tickers might appear when someone tries to cross a different token

Or maybe every time a new price comes, we would need to kill the providers and instantiate again

[RafilxTenfen]

this is so much cleaner than it was before, but thinking of price-feeder as a package for others, would be good to have an func to subscribe new pairs as needed with the provider running

Do these need to be backported for price feeder v1 branch or is it all v2 stuff?
