[Is a member of][User groups] 'Add' button functionality

[carma12]

The 'Add' button functionality allows associating any user group's member to a given user.

To ensure that an Alert component will be displayed after a new addition, a new interface AlertObject has been created to refer to a given alert (const alerts = useAlerts()) passed through props to a children component.

This PR depends on this one to be merged: #297

@pvoborni - There is one comment of yours that refers to outdated code in rpc.ts file and for some reason, I can't add more comments in that thread. Just a heads-up/FYI: I already changed that and now the endpoints look like this:

addToGroups: build.mutation<BatchRPCResponse, [string, string, string[]]>({
      query: (payload) => {
        const toId = payload[0];
        const type = payload[1];
        const listOfMembers = payload[2];
        const membersToAdd: Command[] = [];
        listOfMembers.map((member) => {
          const payloadItem = {
            method: "group_add_member",
            params: [[member], { [type]: toId }],
          } as Command;
          membersToAdd.push(payloadItem);
        });
        return getBatchCommand(membersToAdd, API_VERSION_BACKUP);
      },
    }),

Basically, I added a third parameter that refers to the type, so it would be adapted to the entity provided. WDYT?

The comment might have been attached to outdate code (not sure why), but it was about this implementation and still applies fully.

Understood. I have already corrected the code.
