Ticket: CM-12370
Reviewed By: Roopa, Kanna, Scott E
Testing Done:
This patch also fixes a problem where dhcp6 used to create lease file with
a trailing whitespace. dhcp6 operation were also sometimes using the wrong
pid file. I added some code in the debian.postinst script to correctly
rename these files if they exists when we install/update ifupdown2.
