Debugging is now enabled by default in the containers that are
generated with container_create. "+SYS_PTRACE" has been added to
CAP_DEFAULTS in shdefaults for this.
SSSD 2.10+ runs under non-privileged user 'sssd' and relies on system
capabilities to get access to certain resources like /etc/krb5.keytab.
Not having these capabilities result in SSSD not starting.
Podman has reduced the capabilities granted to containers, and to be
able to start SSSD it is needed to add DAC_READ_SEARCH back.
This patch adds file infra/images/shdefaults to store the defaults used
by ansible-freeipa shell utilities in a contral location.
