Gitlab::Shell namespace CRUD methods

Gitlab::Shell is part of gitlab-ce. This is about methods #add_namespace, #rm_namespace, #mv_namespace.

In addition we should also migrate Gitlab::Shell#exists? while we are here.

service NamespaceService {
  rpc AddNamespace(AddNamespaceRequest) returns (AddNamespaceResponse) {}
  rpc RemoveNamespace(RemoveNamespaceRequest) returns (RemoveNamespaceResponse) {}
  rpc RenameNamespace(RenameNamespaceRequest) returns (RenameNamespaceResponse) {}
  rpc FileExists(FileExistsRequest) returns (FileExistsResponse) {}
}

message AddNamespaceRequest {
  string storage_name = 1;
  string name = 2;
}

message RemoveNamespaceRequest {
  string storage_name = 1;
  string name = 2;
}

message RenameNamespaceRequest {
  string storage_name = 1;
  string from = 2;
  string to = 3;
}

message FileExistsRequest {
  string storage_name = 1;
  string name = 2;
}

message FileExistsResponse {
  bool exists = 1;
}

//  Other response messages are all empty
