Pass memory size calculation to engine based on a 1gib/tgt quota
despite control-plane hugepage allocations taking MD-on-SSD
System-XStream into account when calculating.

Reorganize test cases in server_utils_test.go by splitting error
scenarios into a dedicated test function.

Steps for the author:

  • Commit message follows the guidelines.
  • Appropriate Features or Test-tag pragmas were used.
  • Appropriate Functional Test Stages were run.
  • At least two positive code reviews including at least one code owner from each category referenced in the PR.
  • Testing is complete. If necessary, forced-landing label added and a reason added in a comment.

After all prior steps are complete:

  • Gatekeeper requested (daos-gatekeeper added as a reviewer).
