Liu Jiang 95e8049398 shim: distinguish between runtime id and container id 
There's a misuse of runtime id and container id in Shim::new(). Both
runtime id and container id are needed by shim implentions, so add
parameter `container id` to Shim::new().

Liu Jiang fdd50661f3 shim: add interface Shim::get_task_service() 
Currently Containerd shimv2 runtime only provides task service, but it
may provide more service in future. So add interface
Shim::get_task_service() to get the task service object instead of
"Shim: Task".

Liu Jiang 5197e72f4a shim: do not panic if failed to log to FIFO 
According to Linux FIFO doc, writing to a FIFO without reader may
return errors:
If all file descriptors referring to the read end of a pipe have been
closed, then a write(2) will cause a SIGPIPE signal to be generated
for the calling process. If the calling process is ignoring this
signal, then write(2) fails with the error EPIPE.

When restarting logger servers, there are small race windows that
FifoLogger::log/flush() may encounter IO error and panic. It's not
a good situation to panic due to errors in logging subsystem.

So just ignore those IO errors.
