Subject: [PATCH] kata-deploy: Add runtime config for crio if it does not exist

Rather than add the config for kata-qemu and kata-fc unconditionally,
the script now checks if the runtime config exists.
If it exists, then do not chnage the path for the runtime.
The user may have configured this to a specific path for testing
local chnages.

Fixes #374
