VMware: vmware_tools connection plugin (#55059)

Browse Source 
* variable standardisation and cleanup

- connection_address -> vmware_host
- connection_username -> vmware_user
- connection_password -> vmware_password
- connection_verify_ssl -> validate_certs
- connection_ignore_ssl_warnings -> silence_tls_warnings
- ansible_vmware_tools_vm_path -> ansible_vmware_guest_path
- standardize user/pass vars
- fallback to default ansible conneciton vars
- accept VMware standard env vars:
- note lack of "become" support
- add example usage
- more reasonable default sleep interval
- auto-silence tls warnings if validate_certs=false
- get_option for executable
- remove unsafe 'makedirs_safe'

* executable: support env vars and ini

short_description: Execute tasks inside a VM via VMware Tools
description:
- Use VMware tools to run tasks in, or put/fetch files to guest operating systems running in VMware infrastructure.
- In case of Windows VMs, set C(ansible_shell_type) to C(powershell).
- Does not work with 'become'.
