The ErrorBoundary component has a generic log message that is not
overridable and will aggregate errors from different components. The
ideal scenario is that log tags are configurable so that errors can be
filtered for in log post-processing.
Add the logMetadata: { logCode, logMessage } prop to the ErrorBoundary
component so that log tags are configurable. Default tags are
maintained.
Add specific log metadatas for the client startup error boundary
(logCode: 'app_startup_crash') and the user connection error boundary
(logCode: 'app_crash').
