The linter ruleset should be versionable

[alex-frankel]

At some point we will introduce the ability to treat warnings as errors. At that point, if we add a new linting rule it could be a breaking change, so we should have the ability to pin the linter rule set to a specific version in bicepconfig.json. Something like:

{
  "analyzers": {
    "core": {
      "ruleSetVersion": "x.y.z"
      ...
    }
  }
}

Whatever mechanism is used, ideally Intellisense for rule names (at least core ones) will work based on the rules available only in the specified ruleset version.
