Add support for fetching recent builds in Buildbot 0.9 format in BuildbotSyncer

[Aakash Jain]

As part of supporting Buildbot 0.9, BuildbotSyncer should be able to fetch recent builds from Buildbot 0.9 server. We should add support to handle this in existing perf syncing scripts without breaking any of the current functionality.

We need tests for this. r- due to the lack of tests.

There is no point in manually pushing. Just do:
return content.builds.map((build) => new BuildbotBuildEntry(this, build));

What why `+ ` between "builds?" and "limit="? Please concatenate them instead.

Done. Thanks for the suggestion.

I have tried to break down overall changes into smaller patches. For e.g. this patch add code to just fetch the recent builds (but does not enable this code path yet). Final patch in https://bugs.webkit.org/show_bug.cgi?id=175969 start using all this code and all the test-cases (unit-tests and server-tests) are updated in that.

We need to start testing this code right now, not in the final patch. The whole point of breaking down patches was to make each patch reviewable. And that includes tests for those broken up pieces.

Again, we need a test for this. r-

Use async "() => {" here

and do:
await promise;
assert.deepEqual(content, []);

i.e.
async () => {
    const syncer = BuildbotSyncer._loadConfig(MockRemoteAPI, sampleiOSConfig(), builderNameToIDMap())[1];
    const promise = syncer._pullRecentBuilds(0);
    assert.equal(requests.length, 0);
    await promise;
    assert.deepEqual(content, []);

Ditto about using async await.

Use async

> +            let syncer = BuildbotSyncer._loadConfig(MockRemoteAPI, sampleiOSConfig(), builderNameToIDMap())[1];

Use await.
