NO-ISSUE: add RestartSec=10s for systemd service

[lance5890]

Which issue(s) this PR addresses:

As the default RestartSec is 100ms，The microshift may not startup in default StartLimitBurst(5 times) ; we should expand the systemd RestartSec to 10s，just like the etcd serivce does as follows:

microshift/ansible/roles/install-microshift/files/etcd.service

Line 20 in 032d259

RestartSec=10s

Hi @lance5890. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

We deployed MicroShift on a host with insufficient performance. During startup, we found that the network was not fully configured before the systemd service started, which caused MicroShift to fail to start. After failing more than five times, it stopped attempting to start. The issue was resolved after we manually adjusted the RestartSec=10s.

I noticed you've taken steps to address the problem with StartLimitIntervalSec.
However, I'm afraid that this change needlessly increases the timeout that some feature depend on and I'm hesitant to apply it by default.

I would suggest instead that you use a systemd drop-in to configure required settings to match your environment.

directly extending the RestartSec parameter to 10s might be a bit risky, but I still suggest starting by modifying this value to 1s (compared to the default of 100ms) would resolve most issues
