remove_columnstore_policy()

Remove a columnstore policy from a hypertable or continuous aggregate.

Samples

You see the columnstore policies in the informational views.

Remove the columnstore policy from the cpu table:
```
CALL remove_columnstore_policy('cpu');
```
Remove the columnstore policy from the cpu_weekly continuous aggregate:
```
CALL remove_columnstore_policy('cpu_weekly');
```

`if_exists`	BOOLEAN	`false`	✖	Set to `true` so this job fails with a warning rather than an error if a columnstore policy does not exist on `hypertable`
