Ticket 51079 - container pid start and stop issues
Bug Description: During the container startup, we were incorrectly
checking for the pidfile as we started. We also were not properly
catching sigint, and dscontainer on keyboard int was not passing
some signals through.
Fix Description: Improve signal handling in dscontainer, add sigint
as a caught signal to ns-slapd, and remove the pid file from the container
instance as we do not require it.
