rewriter container could not be stopped with SIG_INT

Start rewriter:

docker network create haf_test
docker run -d --network haf_test  --name=hivemind-postgrest-server registry.gitlab.syncad.com/hive/hivemind:878c8168 postgrest-server --database-url=postgresql://hivemind@172.17.0.2:5432/haf_block_log
docker run --network haf_test -d --name=hivemind_rewriter registry.gitlab.syncad.com/hive/hivemind/postgrest-rewriter:878c8168
docker stop hivemind_rewriter
docker inspect  hivemind_rewriter --format='{{.State.ExitCode}}'

ExitCose is 137, openresty started by container is not killed with SIG_INT, and docker sends SIG_KILL to end processes

Consequences: rewriter is not cleanly closed, affects HAF APi Node setup by adding delay for tries with SIG_INT during compose is being down
