Create custom confirm component

[leandroradusky]

Create a new component to display confirmation custom messages like the ones defined in this mockup or in this one.

The existing component ConfirmationModal serves as a good template but bases all it's logic on the actions of confirming and confirming deletion to display its title and apply the corresponding styling, doesn't allow nor to display custom messages on the buttons neither define actions for them, which are needed by the reporting feature requirements.
