GOBMCN2-162 - backup-dest is optional

[pythiangoryunov]

install-oracle.sh
-- make backup-dest optional
-- ask for backup-dest if no skip-database-config option is used

[pythiangoryunov]

The change to make backup-dest optional. However if --skip-database-config option is not used (then play config-db is in place) then backup-dest is asked

[mfielding]

Although we change the enforcement here, do we need a tag or some other way to actually avoid trying to create the backup dest and backup creation? Or will that be skipped implicitly if we don't use the config-db playbook?

further on if backup destination starts with "/" it will be created in ora-host role
if it starts with "+" (meaning it should point to disk group) it is checked that the disk group exists
