    @vrozov I have replaced `com.codahale.metrics` with last `io.dropwizard.metrics`. 
    Please review.

>                 URL: https://issues.apache.org/jira/browse/DRILL-6282
>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Tools, Build & Test
>    Affects Versions: 1.13.0
>            Reporter: Vitalii Diravka
>            Assignee: Vitalii Diravka
>            Priority: Major
>             Fix For: 1.14.0

> There are three types of metrics-core in Drill: 
> 1. _com.yammer.metrics_, 
> 2. _com.codahale.metrics_, 
> 3. _io.dropwizard.metrics_
> Drill uses only 1 and 2. The last 3 one is used by Hive.
> 1st one has different class full identifiers, but the 2 and 3 ones have the same class full identifiers and maven doesn't know which library to use ([https://github.com/dropwizard/metrics/issues/1044]).
> But I found that 3 one library is used by Hive only for tests, therefore it is not required for Drill and could be excluded from hive-metastore and hive-exec.
> The dependencies conflict is related not only to metrics-core, but to metrics-servlets and metrics-json as well.
> All these metrics should be organized with proper excluding and dependency management blocks.
