Description of problem:
Create migration plan with esxi endpoint on OCP web UI, but the migration plan will be failed with error 'The plan is not ready - StorageMapNotReady' and status of storage map is 'Source storage not found.'

The root cause of failed storage mapping is storage name will be changed to storage id after creating migration plan, for example：source storage name 'esx7.0-matrix' was detected and correct during creating migration plan on OCP web UI, but storage name 'esx7.0-matrix' will be changed to id '10.73.194.35:/vol/s3tzheng393301/s3images/esx7.0' in storage mapping after creating migration plan
