249: Use half of the computer threads for the indexing process by default r=Kerollmops a=irevoire
closes#241
By default, we use only half of the CPU threads when indexing documents; this allows the user to use the search while indexing. Also, the machine will not appear unresponsive when indexing a large batch of documents.
On the special case where a user only has one core, we use it entirely 😄

228: Authentication rework r=curquiza a=MarinPostma
In an attempt to fix#201, I ended up rewriting completely the authentication system we use. This is because actix doesn't allow to wrap a single route into a middleware, so we initially put each route into it's own service to use the authentication middleware. Routes are now grouped in resources, fixing #201.
As for the authentication, I decided to take a very different approach, and ditch middleware altogether. Instead, I decided to use actix's [extractor](https://actix.rs/docs/extractors/). `Data` is now wrapped in a `GuardedData<P: Policy, T>` (where `T` is `Data`) in each route. The `Policy` trait, thanks to the `authenticate` method tell if a request is authorized to access the resources in the route. Concretely, before the server starts, it is configured with a `AuthConfig` instance that can either be `AuthConfig::NoAuth` when no auth is required at runtime, or `AuthConfig::Auth(Policies)`, where `Policies` maps the `Policy` type to it singleton instance.
In the current implementation, and this to match the legacy meilisearch behaviour, each policy implementation contains a `HashSet` of token (`Vec<u8>` for now), that represents the user it can authenticate. When starting the program, each key (identified as a user) is given a set of `Policy`, representing its roles. The later is facilitated by the `create_users` macro, like so:
```rust
create_users!(
policies,
master_key.as_bytes() => { Admin, Private, Public },
private_key.as_bytes() => { Private, Public },
public_key.as_bytes() => { Public }
);
```
This is some groundwork for later development on a full fledged authentication system for meilisearch.

240: Rework error messages r=irevoire a=MarinPostma
Simplify the error messages, and make them more compliant with legacy Meilisearch.
Basically, stop composing the messages, and simply forward the message of inner errors.

230: Logs r=MarinPostma a=irevoire
closes#193
Since we can't really print the body of requests in actix-web, I logged the parameters of every request and what we were returning to the client.

232: Fix payload size limit r=MarinPostma a=MarinPostma
Fix#223
This was due to the fact that Payload ignores the limit payload size limit. I fixed it by implementing my own `Payload` extractor that checks that the size of the payload is not too large.
I also refactored the `create_app` a bit.
