#find_input(input_locator, within: nil, options: {}) ⇒ Object

Similar to find_node, but looking for fillable fields for this cases:

1. label or span(as label) with input hint for input || textarea || @contenteditable
2. capybara lookup by label || plcaeholder || id || name || etc
3. @contenteditable with @placeholder = @locator

returns: Capybara node
