Managed K8S resources should match standalone. (#2288)

[cmacknz]

The CPU and memory requests for a standalone agent were updated to higher values than what is currently used for Fleet managed agents. Update the managed configuration to match the standalone configuration there is no reason for them to be different.

(cherry picked from commit 9c6c5ae)

Manual backport of #2288 since mergify failed to do it
