    HIVE-18130: Update table path to storage parameters when alter a table

    When an managed table is created by Spark, table path information is not only store in
`location` field (first figure), but also in `parameters.path` fields (second figure).
    <img width="445" alt="location" src="https://user-images.githubusercontent.com/1458656/33123050-466c6bdc-cf79-11e7-8b53-85ad7dc83f17.png">

    When hive alter a table, `storage parameter` is ignored. Then, spark cannot access the
table anymore because spark use the parameter.
    
    In this PR, when altering a table, the field `storageDescription.parameters.path` is also
updated, if `path` key exists
