jvpp-benchmark: measure classifyAddDelTable

Synchronously creates classify tables.
By default 20x2s warmup
and 100x2s measurement iterations are performed.

VPP is restarted after each iteration.

Each invocation of classifyAddDelTable uses tables
from precomputed set of size tableSetSize.
Tables from the set are used in round-robin fashion.

Run with:

sudo java -jar ./target/jvpp-benchmark-exec.jar \
ClassifyTableCreateBenchmark

To specify aclSetSize (default=100), use:

sudo java -jar ./target/jvpp-benchmark-exec.jar \
ClassifyTableCreateBenchmark -p tableSetSize=1000

To see more options, use

java -jar ./target/jvpp-benchmark-exec.jar -h
