Configuration of the Solr index URL must currently be done in a
subsection, as follows:
[index]
type = SOLR
[index "solr"]
url = 127.0.0.1
Subsections are also being used for configuration of specific indexes
like the "changes_open" and "changes_closed" subsections that are used
for Lucene indexes, and are documented as "index.name.xyz".
Having the Solr URL configration under a similar subsection may cause
confusion, and it would be more intuitive to configure the URL under
the main index section, like:
[index]
type = SOLR
url = 127.0.0.1
Subsections are being used for configuration of specific indexes like
the "changes_open" and "changes_closed" settings that can be specified
for Lucene indexes which are documented as "index.name.xyz"
Also add missing documentation of the URL parameter.
