Duplicated SSH Config Directives

[grady]

The sshd configuration specified in entrypoint.sh sets up duplicate directives for MaxAuthTries and LoginGraceTime set.

docker-ssh/src/rootfs/entrypoint.sh

Lines 94 to 95 in 8c8f3ee

	echo "MaxAuthTries 5"
	echo "LoginGraceTime 20"

docker-ssh/src/rootfs/entrypoint.sh

Lines 115 to 118 in 8c8f3ee

	# Brute force protection
	echo "MaxSessions 10"
	echo "MaxAuthTries 3"
	echo "LoginGraceTime 15"

Given how sshd processes the config files, the first directive wins, and the less stringent values for these settings are enforced, which can be confirmed by running sshd -T inside the container.

I suggest removing the lines at 94-95 so that only the more stringent settings listed under the # Brute Force Protection section at line 115 are written to the config file and then enforced by sshd.
