running ansible in the yugaware container

In order to run ansible within the yugaware docker container you need to add the python environment this is done with a pywrapper script in the devops bin directory

cd /opt/yugabyte/devops

./bin/pywrapper ansible-playbook ...

three durations when postgresql log_duration is set to true

In the following yugabyte posrgresql logs with some debug turned on

log_duration=true

this is put in ysql_pg.conf via --ysql_pg_conf

why do we have multiple duration times?
