Nginx by default doesn't enable the cache for POST. Why change this behavior here?

It doesn't affect the default behavior of APISIX, which means that user can specify the POST method on APISIX.

Could you sync it to APISIX.pm?

Is it necessary to cache a POST request?
The only I can think of for caching POST requests is that some internal specification forces the consistent use of POST requests……

Here you change the Nginx template, without a configurable setting. This is a change for default havior.

Yes. This is a very rare scenario. The users don't enable the method on APISIX, it doesn't take effect. If users enable it, they need to know what they are doing.

What this PR does / why we need it:
Nginx's proxy_cache_methods directive only allows to specify
GET、POSTandHEAD, so we keep same with Nginx.#4776
