Must-gather download logs available before migration finishes

[mnecas]

isse: must gather custom name use resource name when a resource is deleted and re created, the name stay the same but in the context of must gather, we actually want to get the logs of the specific resource and not the last resource with this name

for example: when debugging the logs of serverX on namespace main from yesterday, serverX today may be a different pod

a fix: use the resource UID instead of its name

When starting the migration the button for Download logs is available before the migration finishes and even without starting the must gather.

taking as this will require more changes then just the name
