VERSION always unknown

[theonedemon]

local VERSION = 'unknown'
if package.search('http.VERSION') then
    VERSION = require('http.VERSION')
end

file VERSION.lua contains in .gitignore and always build package has "unknown" version

issue is related to http-v2 that is now deprecated.

We can implement the similar mechanism for http v1 too, if it is useful. Personally I several times meet the situation, when a user answers "I don't know" for "which version of a module is installed on your system?".

Brief checklist (for a module with Lua/C, pure Lua would differ a bit):

• Correct version in a module installed using tarantoolctl rocks install <module> <version> (from rockspec as well as from src.rock).
• The same for scm-1 (only rockspec).
• The same for tarantoolctl rocks make in a git repository.
• The same for cmake . && make build.
• The same for RPM / Deb packages.

(Am I missed something?)

Isn't it solved by #184?
