Server injected configuration files

This directory contains all the files that will be overridden by the server. The ones in this location are the default ones, and are typically only used when creating a fake swarming_bot.zip file via the appengine/swarming/tools/bot_archive.py script.

• bootstrap.py is served off /bootstrap endpoint. It is user configurable but entirely optional.
• bot_config.py is included in swarming_bot.zip. It is user configurable and is expected to be modified to suit the project's bot management.
• config.json is generated by the server, with the hostname and version of the server. This file exists only so that it can be used by appengine/swarming/tools/bot_archive.py; when the bot is generated by the server, the config in the yield_swarming_bot_files function in appengine/swarming/server/bot_archive.py is used instead.
