docker: warn about low inotify/file-max and missing FUSE at connect
Add a read-only _check_host_readiness() that runs once after the Docker
daemon connection is established. It reads /proc/sys inotify/file-max
limits and /proc/filesystems (for FUSE), and logs a warning with the exact
commands to fix when they are too low for heavy containers -- XRd wants
~4000 inotify instances per node against a stock default of 128.

The server runs unprivileged (only the setuid ubridge helper has root), so
it can only check, not set; the warning tells the admin exactly what to
raise once. Stays silent when the limits are already sufficient.
