Remove direct dependency on google/[email protected]

[hakman]

The tail functionality was removed from google/cadvisor about 3 years ago by google/cadvisor#2445, as it was no longer used.

This functionality is still used here and makes upgrades difficult.

@dims As one of the people on the cAdvisor Core Team, how do you see this approach.
Any suggestions would be appreciated!

@hakman third_party please, like we have in k/k ( https://github.com/kubernetes/kubernetes/tree/master/third_party/forked/golang )

[hakman]

Thanks for the feedback @dims. Updated to use third_party dir, like in k/k.
