Default value for ssh_max_startups should be changed

[joubbi]

The default value for ssh_max_startups in the ssh_hardening role is '10:30:100'.
This same value is also the default for OpenSSHd.
If I have understood the manuals correctly, the default value is not doing any hardening at all.

Describe the solution you'd like
I would like the default value to be changed to 10:30:60.
This is the CIS level 1 recommendation.

Additional context
CIS CentOS 7 benchmark:

5.2.21 Ensure SSH MaxStartups is configured (Automated)
Profile Applicability:
 Level 1 - Server
 Level 1 - Workstation
Description:
The MaxStartups parameter specifies the maximum number of concurrent unauthenticated
connections to the SSH daemon.
Rationale:
To protect a system from denial of service due to a large number of pending authentication
connection attempts, use the rate limiting function of MaxStartups to protect availability of
sshd logins and prevent overwhelming the daemon.
Audit:
Run the following command and verify that output MaxStartups is 10:30:60 or matches
site policy:

# sshd -T -C user=root -C host="$(hostname)" -C addr="$(grep $(hostname)
/etc/hosts | awk '{print $1}')" | grep -i maxstartups
maxstartups 10:30:60

Remediation:
Edit the /etc/ssh/sshd_config file to set the parameter as follows:
maxstartups 10:30:60
Default Value:
MaxStartups 10:30:100
