Description

• Remove need to update diff files to implement changes to operator code.
• Fix project's Operator SDK version.
• Add script to help update project's Operator SDK version.

Testing Instructions

TODO

Operator SDK update

For example, run

./scripts/update_operator_sdk_version.py v1.31.0
# check script logs
patch -p1 --verbose -d pelorus-operator -i current-to-next.diff

Project versions

Just removed -f and -d flags from script. The big difference is for updating operator CRD, you now update a yaml file instaed of a diff file, for example.

Just example of file generated by new script, this file will be deleted prior to merge

[mateusoliveira43]

confirm that change did not modified operator image

[mateusoliveira43]

this works if newest Operator SDK version, 1.31.0, but because of the change, it would need to be updated every time we update its version

My idea is delete this folder, but want opinions
