* Support setting persistent command timeout per task basis
Fixes#42200
* Add variable `ansible_command_timeout` to `persistent_command_timeout`
option for `network_cli` and `netconf` connection plugin so that the
command_timeout can be set per task basis while using `connection=network_cli`
or `connection=netconf`
eg:
```
- name: run copy command
ios_command:
commands:
- show version
vars:
ansible_command_timeout: 40
```
* Modify `ansible-connection` to read command_timeout value from
connection plugin options.
* Add `ansible_command_timeout` to `persistent_command_timeout`
option in `persistent` to support `connection=local` so that
it is backward compatibilty
* To support `connection=local` pass the timeout value as variables
from persistent connection to `ansible-connection` instead of sending
it in playcontext
* Fix CI failure
* Fix review comment
Removes the SSH enforcement because it breaks situations where, for example,
an admin maintains Ansible Tower and another team needs to use Ansible
with the BIG-IP modules, but the Tower admin does not want to install
the F5-SDK on the Ansible Tower instance.
In this situation, the user needs to delegate the execution of the BIG-IP
module to another linux host that does have the dependencies installed.
Usually this is done with delegation, often over SSH. Limiting the SSH
connection here prevents this from working.
