Metadata collection monster eating deprecated lints
This adds the collection of deprecated lints to the metadata collection monster. The JSON output has the same structure with the *new* lint group "DEPRECATED". Here is one of fourteen examples it was able to dig up in Clippy's code:
```JSON
{
"id": "assign_op_pattern",
"id_span": {
"path": "src/assign_ops.rs",
"line": 34
},
"group": "clippy::style",
"docs": " **What it does:** Checks for `a = a op b` or `a = b commutative_op a` patterns.\n\n **Why is this bad?** These can be written as the shorter `a op= b`.\n\n **Known problems:** While forbidden by the spec, `OpAssign` traits may have\n implementations that differ from the regular `Op` impl.\n\n **Example:**\n ```rust\n let mut a = 5;\n let b = 0;\n // ...\n // Bad\n a = a + b;\n\n // Good\n a += b;\n ```\n",
"applicability": {
"is_multi_part_suggestion": false,
"applicability": "MachineApplicable"
}
}
```
And you! Yes you! Sir or Madam can get all of this **for free** in Clippy if this PR gets merged. (Sorry for the silliness ^^)
