Migrate VMs with LUKS-encrypted disks from vSphere

[TylerGillson]

Add support for specifying the --key flag for virt-v2v as per the virt-v2v docs:

Possibly via an additional option in the StorageMap CRD?

@TylerGillson thanks for filing this. we thought about it when trying to deal with TPM - we don't have a way to get it from RHV and even if we get it from vSphere, we won't be able to do much with that data. so asking users to specify the keys and use them this way would make sense, but if the users need to do that per-VM then it goes against the goal to ease mass migrations..

you propose to store it in the storage map because you saw a case that the keys are different for different datastores on the source environment? I'm ok with taking an assumption that the keys are not different per-VM but then I wonder if it wouldn't make more sense to set them per-plan or even per-provider

@ahadas thanks for considering it! I see your point about easing mass migrations. Putting the keys in the plan or provider makes sense to me, since multiple plans can be made if different keys exist for different datastores.
