## What does this PR do?
This PR prepares for removing `httpx`, and reverts back to `requests`.
## Why is this change important?
`httpx` hasn't proven itself to be faster or better than `requests`. On the other
hand it has caused issues on Windows.
=============================================
Please update your environment to use requests instead of httpx.
=============================================
settings.yml:
* outgoing.networks:
* can contains network definition
* propertiers: enable_http, verify, http2, max_connections, max_keepalive_connections,
keepalive_expiry, local_addresses, support_ipv4, support_ipv6, proxies, max_redirects, retries
* retries: 0 by default, number of times searx retries to send the HTTP request (using different IP & proxy each time)
* local_addresses can be "192.168.0.1/24" (it supports IPv6)
* support_ipv4 & support_ipv6: both True by default
see https://github.com/searx/searx/pull/1034
* each engine can define a "network" section:
* either a full network description
* either reference an existing network
* all HTTP requests of engine use the same HTTP configuration (it was not the case before, see proxy configuration in master)
Since #2291 is merged, it is recommend to use::
use_default_settings=True
1. Add a template file use_default_settings.yml::
SEARX_SETTINGS_TEMPLATE="${REPO_ROOT}/utils/templates/etc/searx/use_default_settings.yml"
2. In Chapter "Configuration" recommend to make use of
'use_default_settings=True' and describe it
3. Rewrite of docs/admin/settings.rst
- move chapter 'settings.yml location' to the top
- update and split chapter 'Global Settings'
4. Add environment SEARX_SETTINGS_TEMPLATE to .config.sh
5. Use environment $SEARX_SETTINGS_TEMPLATE in the utils/searx.sh script

This change is backward compatible with the existing configurations.
If a settings.yml loaded from an user defined location (SEARX_SETTINGS_PATH or /etc/searx/settings.yml),
then this settings can relied on the default settings.yml with this option:
user_default_settings:True
A new option is added to engines to hide error messages from users. It
is called `display_error_messages` and by default it is set to `True`.
If it is set to `False` error messages do not show up on the UI.
Keep in mind that engines are still suspended if needed regardless of
this setting.
