kie-issues#821: Kogito Serverless Operator weekly job

[rodrigonull]

ISSUE: apache/incubator-kie-issues#821

This PR updates the operator version to 999.0.00-snapshot to follow the 10 release train and introduces a new weekly Jenkins job for Kogito Serverless Operator that updates the project version to 999.0.0-YYYYMMDD-snapshot locally, build it and deploy the image to quay.io

The weekly job also creates a new tag in the repo with this format: 999.0.0-YYYYMMDD.

I think we can use 10.0.0 since we should follow KIE release train. WDYT?

Perhaps we can set the version to 999-snapshot as discussed here: apache/incubator-kie-issues#763? WDYT @ricardozanini @domhanak

@rodrigonull is the jenkinsfile a "close" copy of an existing one? Wouldn't reuse of a nightly one be possible with some tweaks? Also please can you check that the triggering part is in place? Or please point me to where it's defined.

@jstastny-cz Yes, this Jenkinfile is very similar to the nightly one. I've decided to create a new jenkinfile due to my lack o experience with the pipelines framework and to avoid breaking existing jobs. There are some differences between the nightly and the weekly jobs as described bellow:

for weekly jobs we need to:
Checkout the code from a specific datetime
Update the project version to a specific version (999-YYYYMMDD pattern)
Create and publish a tag in the repository

I think at some point would be nice to refactor this work and create a new job type for weekly jobs and update the nightly jenkinsfiles to support weekly jobs. WDYT?

The PR that adds the triggering is this one: apache/incubator-kie-kogito-pipelines#1177
