(note: to avoid merge conflicts, this PR includes #575)
In order to address NUTCH-2859 host names starting with `*.` (in the config
file `protocols.txt` or in the string rules) are matched as suffixes:
`*.example.org` matches `example.org`, `www.example.org`,
`www.subdomain.example.org`, etc.
Additional improvements:
- allow to read config file protocols.txt from hdfs:// or any file system
supported by Hadoop - useful if the list of host or domains requiring
normalization is large or changes often
- add Javadoc package documentation
- document configuration properties in nutch-default.xml
- reduce the memory footprint by deduplicating protocol strings, so that
same protocol values are references to same objects

> urlnormalizer-protocol: allow to normalize domains
> --------------------------------------------------
>
> Key: NUTCH-2859
> URL: https://issues.apache.org/jira/browse/NUTCH-2859
> Project: Nutch
> Issue Type: Improvement
> Components: plugin, urlnormalizer
> Affects Versions: 1.18
> Reporter: Sebastian Nagel
> Assignee: Sebastian Nagel
> Priority: Major
> Fix For: 1.19
>
>
> The plugin urlnormalizer-protocol normalizes the URL protocol/scheme for a
> given list of hosts to the desired "normal" protocol (usually one of http or
> https). It would be handy to allow to specify domain names as well, so that
> all hosts/subdomains in a given domain are normalized.
> In order to stay backward-compatible this could be done by matching
> {{*.example.org}} as a pattern for all hosts or subdomains of the domain
> {{example.org}}.
