Add initSyncers method in BuildbotTriggerable

[Aakash Jain]

This is part of changes for https://bugs.webkit.org/show_bug.cgi?id=175969.

We should create a separate initSyncers() method in BuildbotTriggerable, which would initialize all BuildbotSyncer. This method could later be updated to support Buildbot 0.9.

Please just do:
triggerable.initSyncers().then(() => triggerable.syncOnce())
here and elsewhere. There's no need in adding the boilerplate of { return ~ }.

This would resolve the promise right away. In order to test your change, we need to do something like:
setTimeout(resolve, 0);
or:
Promise.resolve().then(() => this._syncers = BuildbotSyncer._loadConfig(this._buildbotRemote, this._config))
