executeShellCommand prints secret keys in log

[Nirvanchik]

In changelist #53 we added logging of shell commands that ConnectedDeviceWrapper can execute on device.

Now we want to add a command that puts secret key to device and this logging is silently printing this key in logs, so everyone can see this token. We want to have an API to send such a command with sanitized logging where the secret key could be removed.

I propose the next way:

public synchronized void executeShellCommand(ShellCommand command) throws CommandExecutionException;

interface ShellCommand {
    String getCommand();
    String getLoggedCommand();
    long maxTimeout();
    long getMaxTimeToOutputResponse();
    TimeUnit getMaxTimeUnits();
    IShellOutputReceiver getReceiver();
}

Another problem: no pushFile() method. How can we put a file into device?
