…oint Fixes #1330. Internal customers had a lot of pain with IMA errors and they also feel that spawn mode is too much overhead causing autotuning time to be extra long. This PR stack adds an auto-recovery feature by checkpointing regularly (which is by itself useful for server crash scenarios mentioned in #1330) and then automatically start a new autotune process using previously saved checkpoint if there is an IMA error (next PR). stack-info: PR: #1920, branch: yf225/stack/90
