The previously introduced token caching mechanism [1] reduces token requests to subclouds and also effectively handles Keystone endpoint caching, as the endpoint catalog is cached alongside tokens. We avoid unnecessary creation of `OpenStackDriver` instances solely for retrieving service endpoints, significantly reducing redundant Keystone connections and improving performance. [1] https://review.opendev.org/c/starlingx/distcloud/+/931830 Test Plan: PASS - Deploy a subcloud and verify token caching behavior PASS - Deploy a subcloud with remote install PASS - Prestage a subcloud for install and software deployment, validating token caching during the process PASS - Manage a subcloud for the first time and verify that the initial sync functions as expected. PASS - Unmanage a subcloud, then manage the subcloud again. PASS - BnR scalability test PASS - Test DC orchestration sw-deploy PASS - Scalability test PASS - Geo-Redundancy test PASS - Subcloud network reconfiguration test Story: 2011311 Task: 52217 Change-Id: I2ff8c9c95052a7c3d0c495f481f48c1eb239c253 Signed-off-by: Hugo Brito <hugo.brito@windriver.com>
