[swarming] Ignore STREAM_ALREADY_COMMITTED error.

It appears (based on logs on chrome-swarming) that GetWriteStream
is "eventually consistent", i.e. it may indicate the stream is
pending even after BatchCommitWriteStreams has successfully
finished (even if all calls happen serially, no race conditions).

When this happens and we try to commit the stream, we get back
STREAM_ALREADY_COMMITTED error, which marks the TQ task as
fatally failed (which is technically fine, but noisy).

Ignore this error. It indicates the retry wasn't needed and
everything is OK already.

luci-go: LUCI services and tools in Go

GoReference

Installing

LUCI Go code is meant to be worked on from an Chromium infra.git checkout, which enforces packages versions and Go toolchain version. First get fetch via depot_tools.git then run:

fetch infra
cd infra/go
eval `./env.py`
cd src/go.chromium.org/luci

It is now possible to directly install tools with go install:

go install go.chromium.org/luci/auth/client/cmd/...@latest
go install go.chromium.org/luci/buildbucket/cmd/...@latest
