Support project keys with "invalid" characters

[alexschwarz89]

Is your feature request related to a problem? Please describe. Currently the Cloud API throws an exception and the migration proccess fails if a project key contains a non-supported character like "-".

Describe the solution you'd like There should be an option to sanitize project keys, in order to automatically convert dashes to underscores, or better, convert anything non supported to underscores.

Describe alternatives you've considered Rename the projects before migration.
