Description of problem:
DVMP resource name is created using the name of the PVC. Two PVCs with the same name in two different namespaces will use the same DVMP resource and they will collide.

Version-Release number of selected component (if applicable):
MTC 1.4.0

How reproducible:
Always

Steps to Reproduce:
1. Deploy one application using a pvc in one namespace

for instance (it could be any application using a pvc):
oc process -p NAMESPACE=name1 -f  https://gitlab.cee.redhat.com/app-mig/cam-helper/raw/master/ocp-26160/nginx_with_pv_defaultsc_template.yml | oc create -f -


2. Deploy the same application used in step 1 in another namespace 

oc process -p NAMESPACE=name2 -f  https://gitlab.cee.redhat.com/app-mig/cam-helper/raw/master/ocp-26160/nginx_with_pv_defaultsc_template.yml | oc create -f -

3. Create a migration plan for the namespace created in step 1

4. Create a migration plan for the namespace created in step 2 

5. Run both migrations in parallel using DVM.

Actual results:
Every PVC will have only one DVMP resource. And it will lead to conflicts.

Some times one of the migrations will be stuck forever since it cannot find the right pods in the right namespace.


Sometimes it seems that MTC cannot find out the right secret either (maybe?), and one of the migrations will fail complaining about not being able to authenticate.


Expected results:
Regarding DVMP, we should take into account that 2 PVCs with the same name can exist in 2 different namespaces.



Additional info:

It is probably related with this BZ too https://bugzilla.redhat.com/show_bug.cgi?id=1915717


This is, for instance, the status of dvm and dvmp when we run the 2 migrations and we have problems with the authentication:
