Include option to exclude multiple elements in orb

[manrodrigues]

It would be great as a user experience if we had the option to select multiple elements to delete at once (Currently, all elements must be deleted individually after confirming their usernames)

For example, if I want to exclude all the agents that are offline, there is no way to do it easily.

The goal is to insert something similar to what other platforms have. Google email, for example:

When selecting all the desired elements and pressing the delete option, a confirmation message should be displayed saying "X(number of elements) will be deleted. Do you want to proceed with the deletion?" (or something similar) after confirmation, all elements selected must be removed (non selected elements must be kept.

It must be implemented for:

• Agents
• Agent groups
• Policies
• Datasets
• Sinks
