docs: update rclone about docs
Create a full loop of documentation for rclone about, backends overview
and individual backend pages.

Discussion:
https://github.com/rclone/rclone/pull/4774 relates

Previously pull was requested, in part, under ref
https://github.com/rclone/rclone/pull/4801

Notes:
Introduce a tentative draft see-link format the end of sections to try
rather than lots of in-para links.

Update about.go incl link to list of backends not supporting about.

In list of backends not supporting about, include link to about command
reference.

I appreciate there may be decisions to make going forward about whether
command links should be code formatted, and using proper pretty url
links, but I have fudged that for now.

Update backend pages that do not support about with wording used
previously for ftp - it is in passive voice but I can live with it. (my
own wording and fault). The note is applied to a limitations section. If
one does not already exist it is created (even if there are other
limitations with their own sections)

title: "HTTP Remote"
description: "Read only remote for HTTP servers"
---
{{< icon "fa fa-globe" >}} HTTP
-------------------------------------------------
The HTTP remote is a read only remote for reading files of a
webserver. The webserver should provide file listings which rclone
will read and turn into a remote. This has been tested with common
webservers such as Apache/Nginx/Caddy and will likely work with file
listings from most web servers. (If it doesn't then please file an
issue, or send a pull request!)
Paths are specified as `remote:` or `remote:path/to/dir`.
Here is an example of how to make a remote called `remote`. First
run:
rclone config
This will guide you through an interactive setup process:
```
No remotes found - make a new one
n) New remote
s) Set configuration password
q) Quit config
n/s/q> n
name> remote
Type of storage to configure.
Choose a number from below, or type in your own value
[snip]
XX / http Connection
\ "http"
[snip]
Storage> http
URL of http host to connect to
Choose a number from below, or type in your own value
1 / Connect to example.com
\ "https://example.com"
url> https://beta.rclone.org
Remote config
--------------------
[remote]
url = https://beta.rclone.org
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
Current remotes:
Name Type
==== ====
remote http
e) Edit existing remote
n) New remote
d) Delete remote
r) Rename remote
c) Copy remote
s) Set configuration password
q) Quit config
e/n/d/r/c/s/q> q
```
This remote is called `remote` and can now be used like this
See all the top level directories
rclone lsd remote:
List the contents of a directory
rclone ls remote:directory
Sync the remote `directory` to `/home/local/directory`, deleting any excess files.
rclone sync -i remote:directory /home/local/directory
### Read only ###
This remote is read only - you can't upload files to an HTTP server.
### Modified time ###
Most HTTP servers store time accurate to 1 second.
### Checksum ###
No checksums are stored.
### Usage without a config file ###
Since the http remote only has one config parameter it is easy to use
without a config file:
rclone lsd --http-url https://beta.rclone.org :http:
{{< rem autogenerated options start" - DO NOT EDIT - instead edit fs.RegInfo in backend/http/http.go then run make backenddocs" >}}
### Standard Options
Here are the standard options specific to http (http Connection).
#### --http-url
URL of http host to connect to
- Config: url
- Env Var: RCLONE_HTTP_URL
- Type: string
- Default: ""
- Examples:
- "https://example.com"
- Connect to example.com
- "https://user:pass@example.com"
- Connect to example.com using a username and password
### Advanced Options
Here are the advanced options specific to http (http Connection).
#### --http-headers
Set HTTP headers for all transactions
Use this to set additional HTTP headers for all transactions
The input format is comma separated list of key,value pairs. Standard
[CSV encoding](https://godoc.org/encoding/csv) may be used.
For example to set a Cookie use 'Cookie,name=value', or '"Cookie","name=value"'.
You can set multiple headers, e.g. '"Cookie","name=value","Authorization","xxx"'.
- Config: headers
- Env Var: RCLONE_HTTP_HEADERS
- Type: CommaSepList
- Default:
#### --http-no-slash
Set this if the site doesn't end directories with /
Use this if your target website does not use / on the end of
directories.
A / on the end of a path is how rclone normally tells the difference
between files and directories. If this flag is set, then rclone will
treat all files with Content-Type: text/html as directories and read
URLs from them rather than downloading them.
Note that this may cause rclone to confuse genuine HTML files with
directories.
- Config: no_slash
- Env Var: RCLONE_HTTP_NO_SLASH
- Type: bool
- Default: false
#### --http-no-head
Don't use HEAD requests to find file sizes in dir listing
If your site is being very slow to load then you can try this option.
Normally rclone does a HEAD request for each potential file in a
directory listing to:
- find its size
- check it really exists
- check to see if it is a directory
If you set this option, rclone will not do the HEAD request. This will mean
- directory listings are much quicker
- rclone won't have the times or sizes of any files
- some files that don't exist may be in the listing
- Config: no_head
- Env Var: RCLONE_HTTP_NO_HEAD
- Type: bool
- Default: false
{{< rem autogenerated options stop >}}
### Limitations
`rclone about` is not supported by the HTTP backend. Backends without
this capability cannot determine free space for an rclone mount or
use policy `mfs` (most free space) as a member of an rclone union
remote.
See [List of backends that do not support rclone about](https://rclone.org/overview/#optional-features)
See [rclone about](https://rclone.org/commands/rclone_about/)
