logger: support per-client config

[Yury-Fridlyand]

Describe the feature

Currently, logger config (level and destination) is global. A user may want to create multiple client instances with different logging parameters.

Use Case

var logConfig1 = new LogConfig(LogLevel.ERROR, "/path/to/file");
var logConfig2 = new LogConfig(LogLevel.INFO, null); // log to stdout
var client1 = new Client(logConfig1);
var client2 = new Client(logConfig2);

In that case, [rust core lib] logs produced by both clients will be dumped to stdout with INFO level. Wrepper logs though could be generated on different levels and distributed to different destinations.
