Currently bot_update and tryserver crashes at initialization step if
the input contains multiple gerrit changes. This is not friendly for
CrOS CLs, e.g. crrev.com/c/2536761.

This CL moves the “crash” out of initialization, thus the consumer
of these modules could control which gerrit change to pass to bot_update
and tryserver.

This CL does NOT enable the modules here to support multiple patchset,
but allows consumers to choose one.

Transient network conditions can cause the CIPD client download to fail,
so add a retry to the download.

When using `wget` we additionally retry usually fatal errors like
"connection refused" via `--retry-connrefused`. `curl` also has that
parameter, but it was added more recently in version 7.52.0, which isn't
available on supported platforms like Ubuntu 16.04. Once we raise the
minimum supported version of curl, we should add that parameter as well.

In either case, we retry 3 times and wait 5 seconds between each try,
which matches the retries recently added for Windows.

It is sometimes helpful to do a full build of Chrome using goma while
online and then do incremental builds without goma while offline or with
poor network bandwidth. Turning off goma in gn args triggers a full
rebuild but the GOMA_DISABLED environment variable can be used to
disable goma without triggering a rebuild.

In order to make this feature easier to discover and use this change
adds support for -o/--offline to autoninja. autoninja -h will mention
this flag and autoninja.bat/autoninja.py handle it appropriately. This
means setting the environment variable in autoninja.bat, and using it
to adjust the -j value and stripping it out in autoninja.py.

The bash script that wraps autoninja.py on Linux and OSX did not need
updating because the Python script can emit 'GOMA_DISABLED=1 ninja ...'
and this is executed by bash.

Running "git cl upload" can take a while so I tend to switch to other

This change adds a message saying "Waiting for editor..." to make it
clear who is waiting for whom.
