Create a reusable test framework for testing the kernel module (bats-core?)

[bonifaido]

Problem Statement

Like in #50 we use Bash in CI to test such features as big file upload/download, but we should create a programmable test framework, which is capable of:

• building the kernel module
• loading/unloading the kernel module
• control the kernel module
• load wasm modules (proxywasm, rego, etc.)
• start test severs/clients and make interactions with them to test features and correctness

Proposed Solution

bats-core
