Previously we just made a hard rule that the state storage for Terraform Cloud would never save any intermediate snapshots at all, as a coarse way to mitigate concerns over heightened Terraform Enterprise storage caused by saving intermediate snapshots. As a better compromise, we'll now create intermediate snapshots at the default interval unless the Terraform Cloud API responds with a special extra header field X-Terraform-Snapshot-Interval, which specifies a different number of seconds (up to 1 hour) to wait before saving the next snapshot. This will then allow Terraform Cloud and Enterprise to provide some dynamic backpressure when needed, either to reduce the disk usage in Terraform Enterprise or in situations where Terraform Cloud is under unusual load and needs to calm the periodic intermediate snapshot writes from clients. This respects the "force persist" mode so that if Terraform CLI is interrupted with SIGINT then it'll still be able to urgently persist a snapshot of whatever state it currently has, in anticipation of probably being terminated with a more aggressive signal very soon.
