[SPARK-XXX][BUILD] Update MiMa plugin to 0.1.9.
## What changes were proposed in this pull request?
NOTE: Apache JIRA is down now. I'll update the title as soon as possible.
This PR upgrades MiMa plugin to get bug fixes and new feature (forward
compatibility) for future usage. During upgrade, this PRfixes the following
MiMa error.
```
[info] spark-core: found 1 potential binary incompatibilities while
checking against org.apache.spark:spark-core_2.11:1.6.0 (filtered 891)
[error] * method
this(java.lang.Object,org.apache.spark.AccumulatorParam,scala.Option,Boolean)Unit
in class org.apache.spark.Accumulator does not have a correspondent in current
version
[error] filter with:
ProblemFilters.exclude[DirectMissingMethodProblem]("org.apache.spark.Accumulator.this")
```
Note that the related excluding filter is already registered correctly. It
seems due to the change of MiMa exception result.
```
// SPARK-12896 Send only accumulator updates to driver, not
TaskMetrics
ProblemFilters.exclude[IncompatibleMethTypeProblem]("org.apache.spark.Accumulable.this"),
-
ProblemFilters.exclude[IncompatibleMethTypeProblem]("org.apache.spark.Accumulator.this"),
+
ProblemFilters.exclude[DirectMissingMethodProblem]("org.apache.spark.Accumulator.this"),
```
## How was this patch tested?
Pass the Jenkins build. (MiMa is included.)
