Add "sys_protected" argument to LDAP playbook

This commit adds "sys_protected" optional argument to LDAP playbook
"manage_local_ldap_account.yml". The new argument automates adding
an ldap user to the "sys_protected" group at creation time.
Supported values for the "sys_protected" argument are "yes" and "no",
"no" being the default value.

Test Plan:
PASS: Debian image gets successfully installed in AIO-SX system.
PASS: Configure "secure-inventory" configuration for a standalone
system.
PASS: Successful ldap user creation with membership in "sys_protected"
group, using argument "sys_protected=yes".
PASS: Execute LDAP playbook to create a user with no membership in
"sys_protected" group, using argument "sys_protected=no"
PASS: Execute LDAP playbook to create a user with no membership in
"sys_protected" group without setting argument "sys_protected" to
verify the default value.
PASS: Configure "secure-inventory" configuration for a DC system.
PASS: Test "sys_protected" argument usage for LDAP playbook in a DC
system by creating an ldap user in a "sys_protected" group, both on
the system controller and on a subcloud.
