support for kubernetes contexts was deprecated in docker 20.10 through
b639ea8b89b162c3abe99d3ac90b258c48e2039c, 0793f9639440d8980226485189ce0eb43e0af28b,
and 1d37fb302789c6ce4ba120bc4ad577c92674467f, and removed altoghether in
23.0 through 193ede9b12.
This patch removes the remaining stubs for options that were deprecated
and no longer used.
