--as-json outputs the response as json, this allows you to use tools
like jq on the output which is nice.
--quiet makes it so no output is printed. I added this in case you are
looping Beau and don't want to see the output of every single request.
Example: `seq 10 | xargs -I{} beau request hi --quiet`.
* Added a schema validator.
This allows you to check if the given beau config is valid. Will be used
to improve the CLI and remove schema validation-type errors from the
actual code.
* Added a validate command to the CLI.
This command is a way to test the config file. Eventually it'll probably
be removed and the schema validation will run on every other command. I
have to determine how useful this is and how performance might be
affected.
