A new middleware function is added for admin handlers, including options for modifying certain behaviors. This admin middleware: - sets the handler context via reflection in the request and sends AuditLog - checks for object API availability (skipping it if a flag is passed) - enables gzip compression (skipping it if a flag is passed) - enables header tracing (adding body tracing if a flag is passed) While the new function is a middleware, due to the flags used for conditional behavior modification, which is used in each route registration call. To try to ensure that no regressions are introduced, the following changes were done mechanically mostly with `sed` and regexp: - Remove defer logger.AuditLog in admin handlers - Replace newContext() calls with r.Context() - Update admin routes registration calls Bonus: remove unused NetSpeedtestHandler Since the new adminMiddleware function checks for object layer presence by default, we need to pass the `noObjLayerFlag` explicitly to admin handlers that should work even when it is not available. The following admin handlers do not require it: - ServerInfoHandler - StartProfilingHandler - DownloadProfilingHandler - ProfileHandler - SiteReplicationDevNull - SiteReplicationNetPerf - TraceHandler For these handlers adminMiddleware does not check for the object layer presence (disabled by passing the `noObjLayerFlag`), and for all other handlers, the pre-check ensures that the handler is not called when the object layer is not available - the client would get a ErrServerNotInitialized and can retry later. This `noObjLayerFlag` is added based on existing behavior for these handlers only.
