Allow to configure what are log messages that should be collected by testee-client

Currently all the `console.error` and `console.log` messages are being collected by `testee-client` and sent to `testee-server`.
If the tested application generates a significant amount of log messages, they can interfere with the normal execution of the tests.
A good feature could be the enable/disable the log/error console messages collector.

Start at src/index.js lines 79-88, where console.error and console.log messages are collected and sent to testee-server. Trace how testee-client configuration is handled, then determine how the collector can be enabled or disabled; the work is done when both console message types follow that setting without interfering with normal test execution.
