DRILL-6668: In Web UI, highlight options that are not default values
This commit introduces a new button on the options page that allows a user to reset an option to its system default value.
To simplify things, a tooltip is shown when the mouse hovers over the button. If the option value is already default, the button is disabled.
Currently, the Update button redirects to /option/optionName . This change reuses what we already are using to set the default (using AJAX) and auto-refreshing
Switch [Default] label to [Reset]
