Description of problem:
Running katello-installer --katello-oauth-secret=.. updates pulp oauth and candlepin oauth. While pulp services are restarted to apply the change, tomcat service running tomcat application is not restarted.

This causes problems when e.g. registering a new content host that fails with error

Invalid oauth unit or secret

when running subscription-manager on the Host. (the error is quite confusing, since sub-man can auth to Satellite/Capsule itself properly - the error comes from Satellite internals..)

Checking katello-installer logs, candlepin.conf is updated properly, but tomcat service (or tomcat6 for RHEL6) is not restarted.

Please add the hook to restart tomcat once the candlepin.conf is updated ;-)


Version-Release number of selected component (if applicable):
Sat 6.1.3
katello-installer-base-2.3.20-1.el7sat.noarch
katello-installer-2.3.20-1.el7sat.noarch


How reproducible:
100%


Steps to Reproduce:
1. Have Sat6.1.3 installed (might be RHEL7 relevant only, havent tried on RHEL6)
2. katello-installer --katello-oauth-secret=whateverSecretYouWant
3. Try to register a content host to Sat or Caps


Actual results:
- subscription-manager register fails with:
Invalid oauth unit or secret

- production.log having:

- restarting tomcat service gets rid of the problem


Expected results:
- subscription-manager register succeeds
