Description of problem:

The upgrade failed if some imagestream/template doesn't exist.  Message like 'Error from server: imageStream "jenkins" not found'  was reported.

some imagestream/template may not be installed in v3.0.1. for example jenkins imagestream isn't provided by default.  Custom may also drop some imagestreams or templates. It is better to print warning message rather than abort here.

The upgrade also shouldn't use the DEPRECATED 'oc update'.

Version-Release number of selected component (if applicable):
v3.0.1.0 to v3.0.2.0

How reproducible:
Always

Steps to Reproduce:
1. install openshift v3.0.1
2. run upgrade via ansible
   ansible-playbook openshift-ansible/playbooks/adhoc/upgrades/upgrade.yml

Actual Result:
1) Upgrade abort 'Error from server: imageStream "jenkins" not found'
2) Upgrade use DEPRECATED 'oc update.

FATAL: all hosts have already failed -- aborting

Expected Result:

1) Upgrade doesn't abort for 'non-block' issue.
2) Upgrade install the 'non-existing imagestreams/template' or skip it.
3) Upgrade use 'oc replace **' instead of 'oc update'
