[CPID-354] Improve MariaDB Backup/Restore validation process

Updating etcd chart with added backup validation function empty implementation(subject for future realization). This has to be done because helm-toolkit chart in openstack-helm-infra is now calling that function verify_databases_backup_archives() as part of backup_databases() function implementation:
https://review.opendev.org/c/openstack/openstack-helm-infra/+/853027

Changed apiVersion of etcd cronjob from batch/v1beta to batch/v1 and fixed securityContext for etcd_backup.

Also bumping up HTK version to 0.2.48 from a commit id obtained from merge of https://review.opendev.org/c/openstack/openstack-helm-infra/+/853027 and set proper commit id in this file: tools/helm_tk.sh
