[CodyWMitchell]

Description

Conditionally display items in the dropdown based on the users permissions.

• If the user has sources::write or sources:*:write permissions, display both types of integrations and the option to add cloud integrations.
• If the user has integrations::write, integrations:*:write, or integrations:endpoints:write permissions, display both types of integrations and the option to add 3rd-party integrations.
• If user has neither sets of permissions, then the dropdown is disabled.

@CodyWMitchell just curious, does it also cover creating the integration from the empty state in a scenario when the user has only read permissions?

@fhlavac good point! @CodyWMitchell btw you should filter the tiles on empty state as well.

@fhlavac Good catch! Now the tiles in the empty state should also being showing conditionally based on the permissions.
