Add download link of volumes, templates and ISOs to the download event details

[bernardodemarco]

Description

When the download of templates, ISOs and volumes is finished, a download link is generated and displayed to end users in a notification. However, in situations in which the download process takes a large amount of time, the user's authentication session may be expired by inactivity and, thus, the reference to the link gets lost.

Therefore, this PR proposes to add the templates, ISOs and volumes download links to the details of the TEMPLATE.EXTRACT, ISO.EXTRACT and VOLUME.EXTRACT events, respectively. As a consequence of that, in scenarios that users sessions are expired when downloading such resources, the event details can be accessed by users to retrieve the download link.

Screenshots (if appropriate):

• TEMPLATE.EXTRACT event details:

• ISO.EXTRACT event details:

• VOLUME.EXTRACT event details:

How Has This Been Tested?

• Verified that when the templates extraction process is completed, the TEMPLATE.EXTRACT event description is generated with the template download URL.
• Verified that when the ISOs extraction process is completed, the ISO.EXTRACT event description is generated with the ISO download URL.
• Verified that when the volume extraction process is completed for root disks, the VOLUME.EXTRACT event description is generated with the volume download URL.
• Verified that when the volume extraction process is completed for attached data disks, the VOLUME.EXTRACT event description is generated with the volume download URL.
• Verified that when the volume extraction process is completed for detached data disks, the VOLUME.EXTRACT event description is generated with the volume download URL.
