Omit grep process in nova_api healthcheck.

Browse Source 
Currently, the nova_api healthcheck uses the output
from the ps -ef command passing it to grep looking
for the nova_metadata process. However, the way it's
done currently would print out the grep commmand itself
which would cause a false negative.

 ()[root@undercloud-0 /]# ps -ef | grep nova-metadata
 root       10979    8969  0 10:53 ?        00:00:00
 grep --color=auto nova-metadata

This patch uses pgrep intead, which does not create a
grep process that could match the string, plus it
provides a clearer idea on what we are trying to match.
