[swarming] Add base for pRPC server

This will also be useful for BigQuery schema definition.

Move tasks.proto into swarming.proto, which will contain everything
related to the API.

[swarming] Add BotEvent message and first pRPC RPC

It forces me to define the protos, which will then be leveraged for
BigQuery table.

This also expands the number of visible bot states.

[swarming] Split config and api protos; rename api proto package to swarming.v1

- Moving the protos into different subdirectory makes it clearer what is what.
- Add READMEs to help with this.
- Rename the api package to swarming.v1. This futureproofs the API for an
  eventual v2, if every needed. This is a breaking change for the pRPC client,
  but there's no users yet, so now is a good time to do this change.

[swarming] Rewrite TaskState enum

- Make TaskState extremely detailed.
- Use clear categories and even create a type for these: TaskStateCategory.
- Use a much better bit mask now that enables great queries yet has an efficient
  use of the bitspace and efficient varint encoding. This leaves 16 types of
  state per task state category.
- The bitmask is not useful for BigQuery, since we store the enums as strings.
  That's why TaskStateCategory is useful, we can store it too in BigQuery so
  this makes the BQ queries much simpler when someone doesn't care about the
  subtle sub-state.

Let's block this on migrating out of python to the Go client, since it's going to be slightly more annoying to support it in python.
