Improve perfomance:

[Juliasunn]

The directions that affect server perfomanct are:

• Memory allocations (on heap)
• blocking (threads, concurrency)

Heap memory allocations are time-expensive and lead to fragmentstion Solutions:

• allocate everything that is possible on stack;
• use object pool

What is allocated on heap? Everything that is constructed using std::make shared/unique/etc ... (Handlers, )

[Juliasunn]

Create an Allocator class for allocating memory for buffers in ObjectPool:

- multipart/form-data  buffer (body is char *)
-  LoadMediaHandler: response<http::string_body> buffer (body is std::string)

Example of ObjectPool implementation: https://gist.github.com/Gerold103/0199ac4c2facc2b34ef25f8ea44a0601
