Support declare and find an element with attributes

[hoangtaiki]

For currently we support to declare an element with default Appium selector and text key

element :title_label, :class, 'android.widget.TextView', text: 'Filter Advisors'

But sometimes, we have some elements with same text, same selector and some their attributes are different. To support this, we will implement some new functions to allow we can declare an element with attributes
