c2a33300f5 Feature+Bugfix: Engine websocket management (#360)
* Initial commit tearing down the websocket connection management. The purpose is to remove the traffic monitoring and dropping as syncer.go is a better manager

* Adds a readwrite mutex and helper functions to minimise inline lock/unlocks and prevent races

* Creates new WebsocketType struct to contain all parameters required. Deletes WebsocketReset. Utilises ReadMessageErrors channel for all websocket readmessages to analyse when an error returned is due to a disconnect

* Fixes issue with syncer trying to connect while connecting

* Simplifies initialisation function for websocket. Reconnects and resubscribes after disconnection

* Adds WebsocketTimeout config value to dictate when the websocket traffic monitor should die. Default to two minutes of no traffic activity. Increases test coverage and updates existing tests to work with new technologic. RE-ADDS TESTS I ACCIDENTALLY DELETED FROM PREVIOUS PR

* Removes snapshot override as its always necessary when considering reconnections. Increases test coverage. Re-adds tests that were ACCIDENTALLY DELETED. Removes unused websocket channels. Bug fix for traffic monitor to shutdown via goroutine instead of killing itself

* Fixes gateio bug for authentication errors when null. Adds little entry to syncer for when websocket is switched to rest and then back, you get a log notifying of the return. Fixes okgroup bug where ws message is sent on a disconnected ws, causing panic. Renames setConnectionStatus to setConnectedStatus. Puts connection monitor log behind verbose bool

* Fixes lingering races. Fixes bug where websocket was enabled whether you liked it or not. Removes demonstration test

* Fixes log message, renames unc, removes comments

* Fixes data race

* Removes verbosity, ensures shutdown sets connection status appropriately

* Removes go routine causing CPU spike. Stops timers properly and resets timers properly

* Renames `WsEnabled` to `Enabled`. Increases test coverage. Fixes typos. Handles unhandled errors

* The forgotten lint

* With using RWlocks, removes the channel nil check and relies on !w.IsConnected() to prevent a shutdown from recurring

* Removes extra closure step in the defer as it causes all the issues

* Prevents timer channel hangups. Minimises use of websocket Connect(). Expands disconnection error definition. Removes routine disconnection error handling. Ensures only one traffic monitor can ever be run. Renames subscriptionLock to subscriptionMutext for consistency

* Extends timeout to 30 seconds to cover for non-popular exchanges and non-popular currencies

* Updates test from rebase to use new websocket setup function

* Fixes test to ensure it tests what it says it does

0fbf8b172a Websocket orderbook buffering (#333)
* Initial commit setting up a map orderbook system with a buffer. It will write to the buffer, sort apply to main orderbook and then process.

* Moves namespaces again

* Updates orderbook to use a sweet new WebsocketOrderbookUpdate type to handle all updates whether its using ID or not. So good. Adds many tests

* Starting to implement orderbook update handling per exchange. Updates namespaces again. Hopefuylly will find a way to update via ID not timestamp, too many endpoints dont provide update timestamps

* Changes orderbookbuffer to use BufferUpdate type instead of orderbook.Base to achieve more functionality and no need for type conversion functions. Updates tests

* Updates all instances of ws.orderbook.Update. Simplifies some orderbook logic

* Introduces toggleable buffer. Renames orderbooks. Completes implementation for everywhere but OKGroup due to hash calculation

* Implements orderbook update for okgroup, but forgets about the orderbook hash checking

* Fixes okgroup checksum calculation. Fixes linting issue. Removes redundant Kraken tests.

* Introduces sorting toggle and separates from buffer toggle. Uses benchmarks to highlight performance gains

* Fixes Gemini rate limit and parsing. Removes comments and fixes typos

* Fixes bitfinex orderbook processing

* Inbuilt sorting, minor fixes for websocket implementations. Improves test coverage

* Adds surprise LakeBTC websocket support

* Fixes data race

* Fixes rebasing issues due to namespace movements

* Addresses PR nits: moves folder namespace from ws to websocket. Removes line spaces in imports. Fixes lakebtc websocket returns and defer fucntions. Fixes comments

* Adds poloniex orderook sorting support

* Enables bitstamp and hitbtc orderbook sorting. Fixes poloniex's sorting

* Renames namespaces and combines monitor and connection into wshandler. Removes unused SPOT const. Changes how orderbook stuff is loaded. It is done in startup with a setup. Removes exchange name from loadsnapshot as well

* Removes the connection.go from rebasing issues. Removes error response from functions used in goroutines

* Fixes test with exchange name output change

* Fixes issues where copy and paste and replace all were used poorly
