Response of INFO command is incorrectly parsed in _readyCheck

[Rua-Yuki]

Node version: 10.19.0
ioredis version: 4.16.3

The logic within _readyCheck which parses the response of an INFO query is not fully conformant with this command's response format, and may produce incorrect data in some cases.

For instance, given an INFO response with:

# Server
config_file:Y:\redis\redis.conf

The object generated from parsing this data would contain the following incorrect data:

{
  config_file: 'Y'
}

This issue will occur with any info field containing a colon in the value string, as a result of the key-value parsing logic assuming only two colon-delimited components (key and value) may exist:

I understand that this value is mainly parsed for the intention of checking Redis' loading state, and so complete conformance isn't likely to be an issue here.

However, because this info is eventually exposed under the client's serverInfo field, which some libraries have made use of, there would be some benefit at least in correcting this INFO parser.
