Merge #598
598: Matching query terms policy r=Kerollmops a=ManyTheFish

## Summary

Implement several optional words strategy.

## Content

Replace `optional_words` boolean with an enum containing several term matching strategies:
```rust
pub enum TermsMatchingStrategy {
    // remove last word first
    Last,
    // remove first word first
    First,
    // remove more frequent word first
    Frequency,
    // remove smallest word first
    Size,
    // only one of the word is mandatory
    Any,
    // all words are mandatory
    All,
}
```

All strategies implemented during the prototype are kept, but only `Last` and `All` will be published by Meilisearch in the `v0.29.0` release.

Fuzzing milli

Currently you can only fuzz the indexation. To execute the fuzzer run:

cargo +nightly fuzz run indexing

To execute the fuzzer on multiple thread you can also run:

cargo +nightly fuzz run -j4 indexing

Since the fuzzer is going to create a lot of temporary file to let milli index its documents I would also recommand to execute it on a ramdisk. Here is how to setup a ramdisk on linux:

sudo mount -t tmpfs none path/to/your/ramdisk

And then set the TMPDIR environment variable to make the fuzzer create its file in it:

export TMPDIR=path/to/your/ramdisk
