Allow the socket directory to be directly configured by the shim manager
with reasonable defaults when not set. The default for root users will
still be the same directory under the default state directory. For
non-root users a temp directory will be used as default if the state
directory is not owned by the user.

Send the socket directory from containerd to the shim. The shim still
decides where the socket goes but can use the environment variable
passed from containerd to ensure the socket is placed in the configured
directory with proper permission.
This is needed for some rootless cases which do not have permission to
the default state directory as currently set. The directory being
hardcoded by the shim means it is currently not possible to change the
location the shim will listen at.

Avoid using logrus concepts in the API, use slog style log levels with
integer values and 0 meaning the default "info" level.
