Get the config subset for fs.&lt;scheme&gt;.impl
It can include config for fs.&lt;scheme&gt;.impl and additional config for the subKeys fs.&lt;scheme&gt;.impl.* from the configuration
e.g. for scheme "myScheme", there could be config for fs.myScheme.impl, fs.myScheme.impl.client and fs.myScheme.impl.server
@param scheme scheme name, such as http, hdfs, myscheme
@return config for the particular scheme
