[nvidia-bluefield] Add ability to update aging interval

[vivekrnv]

Why I did it

Default Connection aging interval of 1 sec is too small to be used in testing for consistent results.

Thus provide a way for user to make it customizable.

Please note that, a config-reload or reboot must be run for the changes to take effect
