It fixes tarantoolctl enter and the patchset looks good for me.
Pushed to master and 2.2.

We usually start a commit header from a small letter when it is next to
a prefix; I mean: "box/console: move param handlers into file scope".
Changed it before push.

BTW, I suggest to use `luacheck file.lua` to protect youself from some
kind of mistakes. I use the following .luacheckrc file to reduce amount
of false-positives:
| std = {
| read_globals = {'box', 'require', 'debug', 'pcall', 'xpcall', 'tostring',
| 'tonumber', 'type', 'assert', 'ipairs', 'math', 'error', 'string',
| 'table', 'pairs', 'os', 'select', 'unpack', 'dofile', 'next',
| 'getmetatable', 'setmetatable', 'rawget', 'print', 'shard_status',
| 'loadstring', 'arg',
| },
| globals = {'package', '_G'}
| }
| redefined = False
It is not ideal however, just eliminates some false-positive warns I met
before.
WBR, Alexander Turenko.
