add support of K8s 1.35.2 in sylva

closes #3576 (closed)

reverted changes for rancher 2.14 as per discussions in !6891 (comment 3305318199)

relaxed rancher Helm chart kubeVersion constraint done in - !7723 (merged)

this MR:

• adds support of k8s 1.35.2 for rke2 and kubeadm
• adds support of 1.35.0 for ck8s
• updates renovate conf for rancher-charts to track 109.x.x versions
• cleanup rancher-turtles unit
  • instead of cleaning rancher-turtles unit, the preferred solution was to not allow rancher to install rancher-turtles itself so keeping this unit with customized values and patching cm with ns rancher-turtles-system instead of cattle-turtles-system
• add support of rancher 2.14.x

currently there's no version (latest and pre-release versions) of rancher which supports k8s 1.35 yet, so have to disable rancher for the same

Global config for deployment pipelines

• autorun pipelines

• allow failure on pipelines

• record sylvactl events

Notes:

• Enabling autorun will make deployment pipelines to be run automatically without human interaction
• Disabling allow failure will make deployment pipelines mandatory for pipeline success.
• if both autorun and allow failure are disabled, deployment pipelines will need manual triggering but will be blocking the pipeline

Be aware: after configuration change, pipeline is not triggered automatically. Please run it manually (by clicking the run pipeline button in Pipelines tab) or push new code.
