Detect rule param changes for rolling upgrades and rollback assessment (

elastic#173936)

In this PR, I'm adding a test in the alerting framework to detect
changes in a rule type's params schema that will require a snapshot to
be updated. This snapshot will provide a centralized place to view
history on alerting rule params in case we need to asses risk for
rolling upgrades or rollbacks of a release (serverless). The only rule
types affected are those running in serverless in any of the three
project types.

When a rule type is used in serverless, it must provide one of the
following configuration to their rule type on top of everything else:

```
// Zod schema
schemas: {
  params: {
    type: 'zod',
    schema: UnifiedQueryRuleParams
  },
},

// config-schema
schemas: {
  params: {
    type: 'config-schema',
    schema: EsQueryRuleParamsSchema,
  },
},
```

We are working on documenting guidelines so engineers and response ops
can ensure a change to rule parameters will work properly in rolling
upgrade and rollback scenarios and be part of the PR review process.

NOTE to rule type owners: I pass the same schema used to validate to the
`schemas.params` attribute in the rule type. It will be important to
keep them in sync. Down the road, we plan to make `validate.params`
optional and use the schema as a starting point so it's easier to have a
single variable passed in.

## To verify
1. Make changes to the params schema of the ES query rule type.
```

   excludeHitsFromPreviousRun: schema.boolean({ defaultValue: true }),
```
2. Run the jest integration test to update the snapshot file
```
node scripts/jest_integration.js x-pack/plugins/alerting/server/integration_tests/serverless_upgrade_and_rollback_checks.test.ts -u
```
3. Notice the
`x-pack/plugins/alerting/server/integration_tests/__snapshots__/serverless_upgrade_and_rollback_checks.test.ts.snap`
file got updated
```
    "foo": Object {
      "flags": Object {
        "error": [Function],
      },
      "type": "boolean",
    },
```
