chore: remove unused SetAllocationName

[carolinaecalderon]

Description

The SetAllocationMethod in the ResourceManager interface is not used anywhere, just defined.
Remove all definitions to this method -- best practice for tech debt, only keep code that we use in the codebase.

Test Plan

N/a, just don't break existing intg or e2e tests.

Commentary (optional)
