Currently, calling crio config spits out an entire config file. However, it would be prudent for us to move away from the monolithic config file, in favor of smart defaults, and drop-in files.

However, to do this, there needs to be a way for users to quickly create drop-in files, and have them not override the defaults where they don't need to.

The main advantage to this approach is it allows us to change defaults without as much churn in config files.

This proposal is to change crio config to render the configuration/flags it's passed, and only print the toml for the fields that are different than the default.

Sample could be:
crio --log-level debug config
would only output

[crio]
[crio.runtime]
log_level = "debug"
