Profile config

[mworzala]

Profile configs can only be modified by manually editing the JSON file right now.

A config command:

• git config like: mc profile config {profile_name} {key} {value}
• also kinda git config like: mc config {--global | --profile {profile_name}} {key} {value}
• kafkactl like: mc profile alter {profile_name} --config {key}={value}

Allow config changes in initial creation

• mc install 1.20.1 --config {key}={value}
