[Feature] - Restore a backup into an Astra DB

[clun]

• Restore a backup (both Astra and database)

astra db restore mydb \
  -d,--dest ./tmp

[Jeremya]

It would be preferable to have a parameter named --backup-location instead of --dest.
Should we give the option to restore only one keyspace?
Should we add an option that will confirm everything is set for backup restore to succeed? (like checking backup schema vs mydb schema, backup-location exists...)
