Cacti should show PHP INI locations during install

[cigamit]

Feature Request

Is your feature request related to a problem? Please describe

During the install, we show settings for both the PHP Web and PHP CLI but users don't know what INI files are used for each of those. This results in users having to search their entire drive for all INI files and changes each one to test.

Describe the solution you'd like

Simply show the INI file location during install in the header, like we do for the MySQL config file.
