[fbsync] Add SWAG model weight that only the linear head is finetuned to ImageNet1K (#5793)
Summary: * Add SWAG model that only the linear classifier head is finetuned with frozen trunk weight * Add accuracy from experiments * Change name from SWAG_LC to SWAG_LINEAR * Add comment on SWAG_LINEAR weight * Remove the comment docs (moved to PR description), and add the PR url as recipe. Also change name of previous swag model to SWAG_E2E_V1 (Note: this ignores all push blocking failures!) Reviewed By: jdsgomes, NicolasHug Differential Revision: D36095704 fbshipit-source-id: 4a134412cd8f1366cfb55584a1cdecc568e1a78f
