Error messages should include rule name

Bug Report

• TSLint version: 5.7.0
• TypeScript version: 2.3.4
• Running TSLint via: CLI

TypeScript code being linted

Promise.resolve('foo');

with tslint.json configuration:

{
  "rules": {
    "no-floating-promises": true
  }
}

Actual behavior

Running tslint --project . file.ts reports:

ERROR: /full/path/to/files.ts[1, 1]: Promises must be handled appropriately

Expected behavior

I'd expect something like:

ERROR (no-floating-promises): /full/path/to/files.ts[1, 1]: Promises must be handled appropriately

Sometimes an error might be unexpected and we might want to disable the rule that causes it. When you have a large config, though, it may not be obvious which rule reports a particular error.

ESLint formatters print the name of the rule that detects the error.

Use the verbose formatter by adding -t verbose CLI command.

The rest of the issue is a duplicate of #2228
