This commit removes legacy load and upgrade functionality that's being
replaced by USM. It also modifies the prestage systemcontroller upgrade
check to block prestage if there's a software deployment in-progress.
This commit also removes the check that prevents prestaging if any
uploaded release is not 'deployed'. The prestaging playbook is already
responsible for this logic.
Test Plan:
1. PASS - Run subcloud prestaging and verify that it completes
successfully;
2. PASS - Start the deployment of a software release and attempt
to prestage a subcloud, verify that it fails due to the ongoing
deployment;
3. PASS - On a 24.09 system controller, upload a 24.09.01 patch
and attempt to prestage a subcloud for software deploy using
the parameter --release 24.09 and verify that the prestage
operation is allowed even if the 24.09.01 release is in the
'available' state;
4. PASS - Upload a device image using the "system --os-region-name
SystemController device-image-upload" command and verify that the
image is uploaded to the "/opt/dc-vault/device_images" directory.
5. PASS - Remove the device image and verify that it gets removed from
the "/opt/dc-vault/device_images" directory.
