When trying to create a jenkins instance using jenkins template we see the below expection.

TO TEST IT

oc set env dc jenkins OPENSHIFT_ENABLE_OAUTH=false
then, openshift sso login will be disabled, and we are supposed to be able to login withe the default password which is password
=================================================================

Comment 1 Akram Ben Aissi 2021-06-11 14:51:41 UTC

As discussed on slack, this is related to the upgrade of Jenkins 2.277 which remove acegi-security in favor of spring-security.
This breaks the default password setting for our image which is used when:
```
oc set env dc jenkins OPENSHIFT_ENABLE_OAUTH=false
```
If, openshift oauth is disabled for jenkins, we are using default jenkins authentication by setting password to password or by the value pointed by env: JENKINS_PASSWORD.

The fix consists in using bcrypt instead of sha256 digest which is now considered insecure for storing password. Startup scripts have to be modified as a consequence.

This is what the PR does.
