Add `Methods` to table view for `dsc resource list` about dsc HOT 4 CLOSED

I don't think there's any that don't support get because it's a required field in the resource manifest but not sure about test as that's still an optional field in the resource manifest

from dsc.

Are there any resources that can't support get? Any resource that supports get supports test (either directly implemented or synthetic through DSC), I think.

Even when a resource doesn't implement the test command, DSC is able to use synthetic testing to compare the actual state to the desired state:

When this property isn't defined, DSC uses a synthetic test method for the resource. The synthetic test method:

1. Gets the actual state of the instance using the resource's get method.
2. Compares every defined property of the instance's desired state to the actual state.
3. If the desired state of a property isn't equal to the actual state of that property, DSC reports that the instance isn't in the desired state.

Because the synthetic test only checks for equivalency, it can't accurately test resources with properties that can't be evaluated with equivalency alone. For example, if a resource manages package versions and allows setting the version to latest, DSC would report an instance with a version of 3.1.0 as being out of the desired state, even if 3.1.0 is the latest version of the package.

I think the intent of this right now is to simply expose what the resource advertises it implements. So I would expect it to show get, set, test, and/or export. Although get is currently mandatory, that may or may not change in the future and I think it would be confusing ot users to not see it shown. Similarly, although dsc will synthesize test, I think it makes sense to show whether the resource implements it directly and it's via docs that indicate test is available even if the resource doesn't directly implement it as it does have limitations (direct comparison).

Finally, I would suggest this new column to be between Version and Requires.
