Customize Token Introspection response

[nhosoya]

Feature

A configurable option to customize Token Introspection Response

Why?

There are members that are not implemented, but are defined as OPTIONAL by rfc7662 section-2.2. ( sub, username, and so on )
We want to return these values to our clients.

doorkeeper/lib/doorkeeper/oauth/token_introspection.rb

Lines 61 to 71 in 614ec7d

	# 2.2. Introspection Response
	def success_response
	{
	active: true,
	scope: @token.scopes_string,
	client_id: @token.try(:application).try(:uid),
	token_type: @token.token_type,
	exp: @token.expires_at.to_i,
	iat: @token.created_at.to_i
	}
	end
