fix: change tail package (#1874)
Browse files Browse the repository at this point in the history 
## Description:
When logs were being produced at a rate of greater than 200-300 logs per
second, the `nxadm/tail` would be returning incomplete lines, causing
parsing errors on tailed logs. Switching to using `hpcloud/tail` fixes
this completely when I ran several tests with >1000 logs per second.
(the apis are identically and `hpcloud/tail` seems to be more widely
used) In case this package also fails, I've changd the logic return err
immediately.

## Is this change user facing?
NO
