* 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
