jasonmfehr 3e4fdeece1 IMPALA-12824: Removes the prettyprint_duration Built-in Function 
The prettyprint_duration function was originally
implemented in IMPALA-12824 to work with the workload
management tables which stored durations in integer
nanoseconds. These tables have changed to store decimal
seconds.

The prettyprint_duration function would have required a
large investment of time to make it work with decimal
values, and since the new format is more human readable
anyways, this function has been removed.

Impala supports several categories of built-in functions. These functions let you perform
mathematical calculations, string manipulation, date calculations, and other kinds of data
transformations directly in SQL statements.
</p>
<p>
The categories of functions supported by Impala are:
</p>
<ul>
<li>
<xref href="impala_math_functions.xml#math_functions"/>
</li>
<li>
<xref href="impala_conversion_functions.xml#conversion_functions"/>
</li>
<li>
<xref href="impala_datetime_functions.xml#datetime_functions"/>
</li>
<li>
<xref href="impala_conditional_functions.xml#conditional_functions"/>
