Fixed issues in Cloudera Manager 7.7.3.

Cloudera Bug: OPSAPS-64287 New configuration parameter for Data Analytics Studio to configure header size.
Data Analytics Studio (DAS) has a new, optional parameter named das_application_connector_configs to configure header size.
Cloudera Bug: OPSAPS-63881 Permissions of user directories under /var/lib/ is 700 on RHEL 8.4
This issue applies only when RHEL 8.4 or higher is used. In these versions the /etc/login.defs file has HOME_MODE configured with 700 permissions. Due to this, service directories were incorrectly created with 700 permissions.
