test: KUBESAW-236 update ci scripts

[rsoaresd]

Description

• clean OWNER_AND_BRANCH_LOCATION
• cleanup the pull mechanism in scripts/ci/manage-host-operator.sh and scripts/ci/manage-member-operator.sh (thanks @MatousJobanek)
• delete scripts/ci/collect-logs.sh since we do not use it

P.S. Once this PR is merged, I will delete scripts/ci folder on toolchain-cicd
