Show color in interactive mode (#109)

Browse Source 
This patch introduces an internal _KUBECTX_FORCE_COLOR environment variable
that overrides color output decision.

With this, fzf output shows the color indicators for ctx/ns and choosing the
option with the color works without any extra handling.

Fixes #89.
Fixes #98.
