Build CLI autocomplete functions during/after compile rather than at runtime.

Build CLI autocomplete functions during/after compile rather than at runtime.

Maven exec plugin does not yet have a way to add compile and runtime scope deps to the classpath when executing a jar. This feature should be in version 1.6.0 when that releases.
https://github.com/mojohaus/exec-maven-plugin/issues/60

The pom code so far:
org.codehaus.mojo exec-maven-plugin 1.5.0 generate-auto-complete package exec java true runtime -classpath org.locationtech.geomesa.accumulo.tools.AccumuloRunner "help --autocomplete-function" target/autocomplete.sh
The idea here is to run Runner for the tool set being build with the "help --autocomplete-function" parameters and saving the output in a file that can then be copied to conf/. Update scripts to load autocomplete from new location.

Priority: Minor

Parent: GEOMESA-230

Start with the pom configuration and the command that runs AccumuloRunner with "help --autocomplete-function"; then inspect the scripts that currently load autocomplete functions. Generate the autocomplete output during or after the build, place it in conf/, and update the scripts to load it from that location.
