Need attach_logs_cores task to get gdb of only contrail core files

[Vedamurthy Joshi]

R4.1 Build 53

As in http://anamika.englab.juniper.net:8080/job/kubernetes-sanity3/275/console, it is seen that sometimes there are non-contrail crashes as seen below. We need to skip getting bts for those files

Currently, the task attach_logs_cores gets stuck in gdb prompt causing jobs to not complete
