e2e: move functions related to placement to util/placement.go

[parikshithb]

To improve logging clarity in e2e, we need to refactor the functions responsible for retrieving the current and target clusters. These functions are currently private and located in dractions/retry.go. The goal is to make them public and relocate them to a new file, util/placement.go. This change will help standardize cluster placement logic across deployer types and ensure consistent logging for deploy, undeploy, failover, and relocate actions.

Tasks:

• Identify all functions related to retrieving the current and target clusters in dractions/retry.go.
• Move these functions to a new file, util/placement.go.
• Make the functions public to allow access from other packages.
• Update existing code to reference the new public functions.
• Verify that e2e logs correctly display the current and target clusters during deploy, undeploy, failover, and relocate actions.
