Add required sysctl settings to dockerfile and load in entrypoint

[abale]

Some settings are required in sysctl.conf in order for the container to run without issues.

in dockerfile, write /etc/sysctl.conf with:

net.core.somaxconn=1024
vm.min_free_kbytes=2639550

in memsql-entrypoint.sh, add:

#!/bin/bash
set -e
sysctl -p

Actually, this isn't a valid workaround. The /proc system in the container is locked.

I suggest instead updating the readme to add:

docker run -d --sysctl net.core.somaxconn=1024 --sysctl vm.min_free_kbytes=2639550 -p 3306:3306 -p 9000:9000 -v memsql:/memsql --name=memsql memsql/quickstart

Some users may not be able to set those sysctls - but I like the idea. I will update the readme to include a note about that.
