Add script to analyze installer log for action run times

[ehelms]

I've had this little script for a while, and wanted to stop losing track of where it is. The idea is it analyzes an installer run log file and identifies the actions that took the longest. For example, a recent analysis:

61.42:  Exec[foreman-rake-db:migrate]
39.89:  Exec[pulpcore-manager migrate --noinput]
38.11:  Service[foreman]
26.33:  Service[dynflow-sidekiq@worker-hosts-queue-1]
26.27:  Service[dynflow-sidekiq@worker-1]
25.94:  Exec[foreman-rake-db:seed]
25.57:  Service[dynflow-sidekiq@orchestrator]
7.99:  Exec[pulpcore-manager reset-admin-password --random]
7.36:  Foreman_host[foreman-ip-10-0-168-157.rhos-01.prod.psi.rdu2.redhat.com]
4.13:  Foreman_smartproxy[ip-10-0-168-157.rhos-01.prod.psi.rdu2.redhat.com]
3.27:  Package[mod_ssl]
2.9:  Service[pulpcore-content.service]
2.82:  Service[pulpcore-api.service]
2.27:  Cert[ip-10-0-168-157.rhos-01.prod.psi.rdu2.redhat.com-apache]
2.25:  Exec[pulpcore-manager collectstatic --noinput]
