[SPARK-20967][SQL] SharedState.externalCatalog is not really lazy ## What changes were proposed in this pull request? `SharedState.externalCatalog` is marked as a `lazy val` but actually it's not lazy. We access `externalCatalog` while initializing `SharedState` and thus eliminate the effort of `lazy val`. When creating `ExternalCatalog` we will try to connect to the metastore and may throw an error, so it makes sense to make it a `lazy val` in `SharedState`. ## How was this patch tested? existing tests.
