add setup options to provider docs

* Add a first description of the config options for csaf_provider.
 * Change option name from `domain` to `canonical_prefix_url`
    to make the usage more intuitively. Use`https` in the default,
    if unset.

+## Provider options
+Provider has many config options described as following:
+
+ - password: Authentication password for accessing the CSAF provider.
+ - key: The private OpenPGP key.
+ - folder: Specify the root folder. Default: `/var/www/`.
+ - web: Specify the web folder. Default: `/var/www/html`.
+ - tlps: Set the allowed TLP comming with the upload request (one or more of "csaf", "white", "amber", "green", "red").             
+   The "csaf" selection lets the provider takes the value from the CSAF document.         
+   These affects the list items in the web interface.      
+   Default: `["csaf", "white", "amber", "green", "red"]`.
+ - upload_signature: Send signature with the request, an additional input-field in the web interface will be shown to let user enter an ascii armored signature. Default: `false`.
+ - openpgp_url: URL to OpenPGP key-server. Default: `https://openpgp.circl.lu`.
+ - canonical_url_prefix: start of the URL where contents shall be accessible from the internet. Default: `https://$SERVER_NAME`.
+ - no_passphrase: Let user send password with the request, if set to true the input-field in the web interface will be disappeared. Default: `false`.
+ - no_validation: Validate the uploaded CSAF document against the JSON schema. Default: `false`.
+ - no_web_ui: Disable the web interface. Default: `false`.
+ - dynamic_provider_metadata: Take the publisher from the CSAF document. Default: `false`.
+ - publisher: Set the publisher. Default: `{"category"= "vendor", "name"= "Example", "namespace"= "https://example.com"}`.
+ - upload_limit: Set the upload limit  size of the file. Default: `50 MiB`.
