[Proposal] Introduce functional tests for the module

[dedok]

Description

Many companies have CI/CD process which runs testing for the build of nginx. It prevents to have unsupported modules (for example: one module can break another module, or updating of 3rd party: for example openssl version)

Proposal

Introduce functional test using python 3 test framework that can be reused in CI/CD process to test that module works as expected.

Emmm, I must admit that I was lazy at the beginning time then missed it, but I still don't have a good idea until now.

Because I found that nginx functional testing seems to rely heavily on perl, which I am not familiar with. It would be very helpful if it can be implemented using the python3 test framework.

[dedok]

Well, I don't like nginx perl framework also, for example I use it, but very very limited. I can propose some of possible solution based on python tests framework that some of developers are using even for testing nginx. Give me about 1 or 2 weeks to collect references and prepare PoC for this module.

[dedok]

First step: create a branch, introduce a PoC and introduce it to @phuslu .
What we need at least to test:
(1) Compatibility with nginx configuration (variables, map {}, maybe ?njs capture?).
(2) General logic of the work of the module.
(3) This should be complicated to run and should be compatible with GH CI/CD.

Thanks, please go ahead at your own pace.
