Make LetsEncrypt order expiration shorter

What does this MR do?

Problem to solve:

1. We currently don't handle Let's Encrypt errors properly: #30146 (closed)
2. We just wait untill Acme Order is expired and retry
3. The default expiration time for them is 1 week

Most common scenario:

1. User adds domain and verifies it quickly(before pages-daemon have a chance to update the config)
2. GitLab creates Let's Encrypts order
3. Let's Encrypt tries to verify pages domain but hits 404(pages daemon still doesn't know about the domain)
4. Order is in the failed state and will be tried only when expired

This MR just limits the lifetime of Acme Order to 2 hours. It's a workaround, but it fixes a very annoying issue.
