Check_haproxy script looking for Auth in incorrect file

[Benard Okolie]

Currently the check_haproxy.sh script gains authentication using the following variable:

AUTH=$(grep -r "stats auth" /etc/haproxy | awk 'NR=1{print $4}')

The problem is if the authentication credentials are changed a backup file is created in the same directory, which still contains the old credentials. This can cause the problem with the check.

This problem can be solved by grepping for stats inside the file rather than the directory

AUTH=$(egrep "stats auth" /etc/haproxy/haproxy.cfg | awk 'NR=1{print $3}')

Moving bug to charm-helpers as that is the source for the check_haproxy.sh script.

Regression: This check fails now

The grep output has changed but the awk match was not changed accordingly.
