(nexus-repository-migrator) Adds Longer Timeout to AttemptMigration

The post-migration launch process can take significantly longer than normal, due to the additional work Nexus is doing.

This change adds a configurable timeout to the Wait-NexusAvailability command, and uses it in the Nexus-Repository-Migrator package to increase the timeout from 3 minutes to 15.
