[Feat] Develop ansible module for RSYSLOG under Cluster Management namespace

[george-ghawali]

Add PC v4 RSYSLOG server management modules

Modules

• ntnx_rsyslog_servers_v2 — Create, update, delete RSYSLOG server configurations on a Nutanix cluster (server name, IP address, port, network protocol, log modules)
• ntnx_rsyslog_servers_info_v2 — Fetch a specific RSYSLOG server by ext_id or list all RSYSLOG servers for a given cluster

Requirements

• RSYSLOG servers: create, update, delete (server name, IPv4/IPv6 address, port, network protocol: UDP / TCP / RELP, log modules with severity levels)
• RSYSLOG servers: idempotency check on update (field-level diff comparison)
• RSYSLOG server info: fetch by ext_id or list all servers for a cluster_ext_id

Todo

• Client SDK (ntnx_clustermgmt_py_client), get_spec()
• Ansible spec & spec validator
• Sanity test
• Integration test
• Documentation
• Examples
