When we rewrite alias requests, after filtering down to only those that the user is authorized to see, it can be that there are no aliases remaining in the request. However, core Elasticsearch interprets this as _all so the user would see more than they are authorized for. To address this, we previously rewrote all such requests to have aliases `"*"`, `"-*"`, which would be interpreted when aliases are resolved as nome. Yet, this is only needed for get aliases requests and we were applying it to all alias requests, including remove index requests. If such a request was sent to a coordinating node that is not the master node, the request would be rewritten to include `"*"` and `"-*"`, and then the master would authorize the user for these. If the user had limited permissions, the request would fail, even if they were authorized on the index that the remove index action was over. This commit addresses this by rewriting for get aliases and remove aliases request types but not for the remove index.
