This patch was inspired by the discussion around PR-2882 [2]. The goals of this
patch are:
1. Convert plugin searx.plugin.limiter to normal code [1]
2. isolation of botdetection from the limiter [2]
3. searx/{tools => botdetection}/config.py and drop searx.tools
4. in URL /config, 'limiter.enabled' is true only if the limiter is really
enabled (Redis is available).
This patch moves all the code that belongs to botdetection into namespace
searx.botdetection and code that belongs to limiter is placed in namespace
searx.limiter.
Tthe limiter used to be a plugin at some point botdetection was added, it was
not a plugin. The modularization of these two components was long overdue.
With the clear modularization, the documentation could then also be organized
according to the architecture.

To test:
- check the app works without the limiter, check `/config`
- check the app works with the limiter and with the token, check `/config`
- make docs.live .. and read

A blocklist and a passlist can be configured in /etc/searxng/limiter.toml::
[botdetection.ip_lists]
pass_ip = [
'51.15.252.168', # IPv4 of check.searx.space
]
block_ip = [
'93.184.216.34', # IPv4 of example.org
]

For correct determination of the IP to the request the function
botdetection.get_real_ip() is implemented. This fonction is used in the
ip_limit and link_token method of the botdetection and it is used in the
self_info plugin.
A documentation about the X-Forwarded-For header has been added.

To activate the ``link_token`` method in the ``ip_limit`` method add the
following to your ``/etc/searxng/limiter.toml``::
[botdetection.ip_limit]
link_token = true
