[SPARK-13890][SQL] Remove some internal classes' dependency on SQLContext
## What changes were proposed in this pull request?
In general it is better for internal classes to not depend on the external
class (in this case SQLContext) to reduce coupling between user-facing APIs and
the internal implementations. This patch removes SQLContext dependency from
some internal classes such as SparkPlanner, SparkOptimizer.
## How was this patch tested?
Existing unit/integration tests.
