scylladb overrides some of seastar logging related options with its
own options by applying them with `logging::apply_settings()`. but
we fail to inherit `with_color` from Seastar as we are using the
designated initializer, so the unspecified members are zero initialized.
that's why we always have logging message in black and white even
if scylla is running in a tty and `--log-with-color 1` is specified.
so, make the debugging life more colorful, let's inherit the option
from Seastar, and apply it when setting logging related options.
