Adding the ability to set timeout & log level values from CLI flags, and
adding the ability to set k8s & in-cluster values from config file. The
values from the flag takes precedence over the config file.
Test Plan:
PASS Timeout option is set correctly when using the CLI flag
PASS Log level option is set correctly when using the CLI flag
PASS k8s option is set correctly when explicitly set in the config
file, and the flag was not raised
PASS in-cluster option is set correctly when explicitly set in the
config file, and the flag was not raised
