      Right now the server metric `query.planCacheTotalSizeEstimateBytes` refers to the classic plan cache. We need to update this metric when we introduce the SBE plan cache.

      Three options proposed by david.storch:

      1. Make this metric reflect the sum of the sizes of the classic plan caches and the SBE plan cache.
      2. Make this metric reflect the size of the classic plan caches only, omitting the size of the SBE plan cache.
      3. Make this metric reflect the size of the classic plan caches only, and introduce a new metric indicating the size of the SBE plan cache.
