Bump shard02 shard03

[roivaz]

• Remove AKS mgmt cluster sizing overrides for e2e-parallel job
• Bump slot counts for dev e2e shard02 and shard03

Depends on Azure/ARO-HCP#5895

Summary by CodeRabbit

This PR updates OpenShift CI infrastructure for ARO HCP workflows by removing the temporary AKS management cluster sizing override from the e2e-parallel provisioning path, so leased MSI container jobs no longer get special MGMT pool sizing treatment. It also expands the available slot capacity for the ARO HCP dev e2e shard02 and shard03 resources, increasing the number of reusable quota slices to support more parallel execution.

Walkthrough

This PR modifies the ARO-HCP provisioning script to apply an MGMT pool minCount override only when LEASED_MSI_CONTAINERS is unset (healthcheck workflows), removing the prior lease-based sizing override. Separately, it expands boskos dev-shard2 and shard3 slot resource generation from 3 to 6 slots.

Changes

ARO-HCP Provisioning and Boskos Slot Configuration

Layer / File(s)	Summary
MGMT pool sizing override for healthcheck ci-operator/step-registry/aro-hcp/provision/environment/aro-hcp-provision-environment-commands.sh	Replaces the lease-based MGMT sizing override with a guard that forces mgmt.aks.userAgentPool.minCount to 1 when LEASED_MSI_CONTAINERS is empty/unset, removing the prior larger-sizing branch.
Boskos shard slot expansion core-services/prow/02_config/generate-boskos.py, core-services/prow/02_config/_boskos.yaml	Expands the aro-hcp-dev-shard2-slot generation loop from 3 to 6 iterations and adds corresponding -03 through -05 entries for shard2 and shard3 slot names in the generated config.

Check name	Status	Explanation
Title check	✅ Passed	The title is concise and refers to the shard02/shard03 slot-count increase, which is a real part of the changeset.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names	✅ Passed	Touched files are a shell script and Boskos config; no It/Describe/Context/When titles were added or changed.
Test Structure And Quality	✅ Passed	No Ginkgo test code was changed; the PR only touches a provisioning shell script and generated Boskos config, so the listed test-quality checks don’t apply.
Microshift Test Compatibility	✅ Passed	Only a shell script and Boskos configs changed; no Ginkgo e2e tests or MicroShift-sensitive test code were added or modified.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	No Go test sources changed; the PR only updates config/shell/python, so no new Ginkgo e2e tests or SNO assumptions were introduced.
Topology-Aware Scheduling Compatibility	✅ Passed	No topology-sensitive scheduling was added; changes only adjust CI provisioning sizing and Boskos slot counts, with no affinities, selectors, spreads, or PDBs.
Ote Binary Stdout Contract	✅ Passed	Changed files are a shell step, a YAML config, and a Python generator; no process-level stdout writes were added to any OTE binary entrypoint.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	PR only changes config generation and provisioning shell logic; no new Ginkgo tests or IPv4/public-internet assumptions were added.
No-Weak-Crypto	✅ Passed	Touched files only adjust mgmt sizing and Boskos slot counts; scans found no weak-crypto primitives or secret/token comparisons.
Container-Privileges	✅ Passed	Touched files are a shell script and Boskos config/generator; no privileged/hostPID/hostNetwork/allowPrivilegeEscalation settings were added.
No-Sensitive-Data-In-Logs	✅ Passed	PASS: The PR only adjusts cluster sizing and Boskos slot counts; no new logging of secrets, tokens, PII, or hostnames was added in the changed hunks.
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
