* zabbix: tls_issuer -> ca_cert

* bigip_device_auth_ldap: standardize tls params

- ssl_check_peer -> validate_certs
- ssl_client_cert -> client_cert
- ssl_client_key -> client_key
- ssl_ca_cert -> ca_cert

* vdirect: vdirect_validate_certs -> validate_certs

* mqtt: standardize tls params

- ca_certs -> ca_cert
- certfile -> client_cert
- keyfile -> client_key

* pulp_repo: standardize tls params

remove `importer_ssl` prefix

* rhn_register: sslcacert -> ca_cert

* yum_repository: standardize tls params

The fix for yum_repository is not straightforward since this module is
only a thin wrapper for the underlying commands and config.  In this
case, we add the new values as aliases, keeping the old as primary,
only due to the internal structure of the module.

Aliases added:
- sslcacert -> ca_cert
- sslclientcert -> client_cert
- sslclientkey -> client_key
- sslverify -> validate_certs

* gitlab_hook: enable_ssl_verification -> hook_validate_certs

* Adjust arguments for docker_swarm inventory plugin.

* foreman callback: standardize tls params

- ssl_cert -> client_cert
- ssl_key -> client_key

* grafana_annotations: validate_grafana_certs -> validate_certs

* nrdp callback: validate_nrdp_certs -> validate_certs

* kubectl connection: standardize tls params

- kubectl_cert_file -> client_cert
- kubectl_key_file -> client_key
- kubectl_ssl_ca_cert -> ca_cert
- kubectl_verify_ssl -> validate_certs

* oc connection: standardize tls params

- oc_cert_file -> client_cert
- oc_key_file -> client_key
- oc_ssl_ca_cert -> ca_cert
- oc_verify_ssl -> validate_certs

* psrp connection: cert_trust_path -> ca_cert

TODO: cert_validation -> validate_certs (multi-valued vs bool)

* k8s inventory: standardize tls params

- cert_file -> client_cert
- key_file -> client_key
- ca_cert -> ca_cert
- verify_ssl -> validate_certs

* openshift inventory: standardize tls params

- cert_file -> client_cert
- key_file -> client_key
- ca_cert -> ca_cert
- verify_ssl -> validate_certs

* tower inventory: verify_ssl -> validate_certs

* hashi_vault lookup: cacert -> ca_cert

* k8s lookup: standardize tls params

- cert_file -> client_cert
- key_file -> client_key
- ca_cert -> ca_cert
- verify_ssl -> validate_certs

* laps_passord lookup: cacert_file -> ca_cert

* changelog for TLS parameter standardization
