Re-land "Bump LogDog Stable, remove API v1."

This reverts commit 603490c636b1da5e2425388c0a41476e6bcf5e57, which
reverted commit 7a02e109f530c978854ea364649a286866612462. The commit was
reverted due to a bug in LogDog/Annotee which stripped STEP_LOG_LINES
even when tee'ing text. This bug was fixed in:
https://github.com/luci/luci-go/commit/3b9b350e96778cdf0bd6381a2b3c23503faed52d

The canary has passed a round of builds successfully on Infra waterfall,
