K8SPS-704 use RestoreBackupSource instead of PerconaServerMySQLBackupStatus

[nmarukovich]

CHANGE DESCRIPTION

Problem:
Short explanation of the problem.
PerconaServerMySQLRestoreSpec.BackupSource is typed as PerconaServerMySQLBackupStatus. A status struct used as spec exposes fields the user can set but that do nothing

Cause:
Short explanation of the root cause of the issue if applicable.

Solution:
BackupSource now has its own type with the two fields that matter:

type RestoreBackupSource struct {
	Destination BackupDestination  `json:"destination,omitempty"`
	Storage     *BackupStorageSpec `json:"storage,omitempty"`
}

Note:

this PRs

• #1490
• percona/percona-helm-charts#934

add new fields to PerconaServerMySQLBackupStatus which currently are propagated to the restore as well because we use the same struct. So depending on the order of merging, your PR or the backup-size PR would need to adopt the changes.
