Can limit-req or limit-count use keys from headers like "authorization" or from query parameters like "teant" or whatever?

[13140983173]

Description

I found documentation that says only ["remote_addr", "server_addr", "http_x_real_ip", "http_x_forwarded_for", "consumer_name"] could be used as key, refers to https://apisix.apache.org/zh/docs/apisix/plugins/limit-req

Environment

• APISIX version (run 2.15.0):

Set the key_type to vars and you can use the variables you want, for instance, if you want to use a HTTP header, use variable http_header_name, where header_name is the name of the HTTP header.

Is this documented somewhere? I can see in https://apisix.apache.org/docs/apisix/plugins/limit-req/ that the valid values are ["var", "var_combination"]

@tokers just want to say thanks it also worked for me using this conf: "key_type": "var" and "key": "$http_my_header_name" This save me a lot of time.
