Provide a way to log file into test

[nvborisenko]

Currently user may use:

any_log_framework.Info("my dog {rp#file#" + filePath + "}")` // and then log framework appender tries to conver it to known message

At the same time we have:

ReportPortal.Shared.Log.Info("my message")

What if we have overloaded method to accept FileInfo?

ReportPortal.Shared.Log.Info(new FileInfo(<path_to_the_file>))

[nvborisenko]

This is easier than https://github.com/reportportal/commons-net/issues/27

@nvborisenko Is it still relevant? Because I see overloaded method like:

[nvborisenko]

yes, we can do something like

void Info(string message, System.IO.FileInfo file)
