Resource logging with autometric

crew 0.10.0

• Give full worker name in the worker launch error message (@multimeric).
• Start the controller automatically in more methods.
• Add an r_arguments argument to supply command line arguments to R for workers (#175, @rpruim).
• Add a cancel() controller method to cancel one or more tasks.
• Call cancel(all = TRUE) from terminate() as a safeguard.
• Make client$dispatcher a ps::ps_handle() handle and add a new client$client handle for the current process.
• To passively log memory usage when log_resources is given, the controller now calls log() as a side effect in most controller methods, with throttling to preserve speed.
• Return a status and status code from pop() etc.
• New internal function as_monad() makes error reporting more consistent.
• Use path.expand() on local log files.
• Switch to Rscript.
• Print session info from crew_worker() before attempting to dial into mirai.
• Add asyncdial = FALSE back to mirai::daemon() call.
• Deprecate local_log_directory and local_log_join in favor of crew_options_local() and the options_local argument.
• Add crew_options_metrics() and the options_metrics argument for recording resource metrics (#178).
• Add a new logging.Rmd vignette to explain best practices for logging and resource usage metrics (#178).
