* SyncManager: Optimise and fixes This is a fairly invasive change which addresses the amount of work the sync manager does each cycle and the cycle intervals. We switch to using discrete locks for each type of work on each pair, so each worker can take a discrete chunk of work safely. For performance and simplicity we now use a map for the currencyPairs. * fix reporting when a websocket is reconnected * fix not switching REST off after websocket available again * fix race condition in isProcessing flag This PR still could go further by avoiding cycling through everything each time, and by pushing some one-time work for adding enabled pairs down to a later stage off the hot path. This was the smallest chunk of refactoring I felt could address everything without changing too much. Significant manual testing done with a variety of Timeouts to test for edgecases and handling. * SyncManager: Fix ticker/orderbook tracker linked * SyncManager: Fix sync complete logging in update * SyncManager: Fix pair format breaking sync key Kraken seems to always switch to XBT_USDT format, but websockets still pass around XBTUSDT format. Just to be safe this just removes the delimiter to avoid any such issues * SyncManager: Remove unused error * SyncManager: Remove unused IsProcessing flag * SyncManager: Fix Update test add() pair format We had to unify pair format inside sync manager, so test needs to do the same
