> {{instance.dfs.uri}} and {{instance.dfs.dir}} are no longer needed with the {{instance.volumes}}
property.
> Together, these two fields are needed for upgrades from relative paths, but full URIs
for volumes should be specified in the {{instance.volumes}} set.
> Instead of appending {{instance.dfs.dir}} to every volume, which is a bit confusing,
they should be specified explicitly in the {{instance.volumes}}.
> Example:
> {code}
>  <property>
>     <name>instance.volumes</name>
>     <value>hdfs://nn1/accumulo</value>
>   </property>
> {code}
> should be equivalent to
> {code}
>  <property>
>     <name>instance.dfs.uri</name>
>     <value>hdfs://nn1</value>
>   </property>
>  <property>
>     <name>instance.dfs.dir</name>
>     <value>/accumulo</value>
>   </property>
> {code}
> This change simplifies the semantics of configuring volumes for Accumulo to use for storage,
and is a bit more obvious that we're logically configuring filesystem volumes, not "namenode
URIs".
