### What changes were proposed in this pull request?
This PR proposes to use a proper built-in exceptions instead of the plain `Exception` in Python.
While I am here, I fixed another minor issue at `DataFrams.schema` together:
```diff
- except AttributeError as e:
- raise Exception(
- "Unable to parse datatype from schema. %s" % e)
+ except Exception as e:
+ raise ValueError(
+ "Unable to parse datatype from schema. %s" % e) from e
```
Now it catches all exceptions during schema parsing, chains the exception with `ValueError`. Previously it only caught `AttributeError` that does not catch all cases.
### Why are the changes needed?
For users to expect the proper exceptions.
### Does this PR introduce _any_ user-facing change?
Yeah, the exception classes became different but should be compatible because previous exception was plain `Exception` which other exceptions inherit.
### How was this patch tested?
Existing unittests should cover,

### What changes were proposed in this pull request?
Currently, only the non-static public SQL configurations are dump to public doc, we'd better also add those static public ones as the command `set -v`
This PR force call StaticSQLConf to buildStaticConf.
### Why are the changes needed?
Fix missing SQL configurations in doc
### Does this PR introduce any user-facing change?
NO
### How was this patch tested?
add unit test and verify locally to see if public static SQL conf is in `docs/sql-config.html`

### What changes were proposed in this pull request?
Spark `ConfigEntry` and `ConfigBuilder` missing Spark version information of each configuration at release. This is not good for Spark user when they visiting the page of spark configuration.
http://spark.apache.org/docs/latest/configuration.html
The new Spark SQL config docs looks like:
```
> SET -v
spark.sql.adaptive.enabled false When true, enable adaptive query execution.
spark.sql.adaptive.nonEmptyPartitionRatioForBroadcastJoin 0.2 The relation with a non-empty partition ratio lower than this config will not be considered as the build side of a broadcast-hash join in adaptive execution regardless of its size.This configuration only has an effect when 'spark.sql.adaptive.enabled' is enabled.
spark.sql.adaptive.optimizeSkewedJoin.enabled true When true and adaptive execution is enabled, a skewed join is automatically handled at runtime.
spark.sql.adaptive.optimizeSkewedJoin.skewedPartitionFactor 10 A partition is considered as a skewed partition if its size is larger than this factor multiple the median partition size and also larger than spark.sql.adaptive.optimizeSkewedJoin.skewedPartitionSizeThreshold
spark.sql.adaptive.optimizeSkewedJoin.skewedPartitionMaxSplits 5 Configures the maximum number of task to handle a skewed partition in adaptive skewedjoin.
spark.sql.adaptive.optimizeSkewedJoin.skewedPartitionSizeThreshold 64MB Configures the minimum size in bytes for a partition that is considered as a skewed partition in adaptive skewed join.
spark.sql.adaptive.shuffle.fetchShuffleBlocksInBatch.enabled true Whether to fetch the continuous shuffle blocks in batch. Instead of fetching blocks one by one, fetching continuous shuffle blocks for the same map task in batch can reduce IO and improve performance. Note, multiple continuous blocks exist in single fetch request only happen when 'spark.sql.adaptive.enabled' and 'spark.sql.adaptive.shuffle.reducePostShufflePartitions.enabled' is enabled, this feature also depends on a relocatable serializer, the concatenation support codec in use and the new version shuffle fetch protocol.
spark.sql.adaptive.shuffle.localShuffleReader.enabled true When true and 'spark.sql.adaptive.enabled' is enabled, this enables the optimization of converting the shuffle reader to local shuffle reader for the shuffle exchange of the broadcast hash join in probe side.
spark.sql.adaptive.shuffle.maxNumPostShufflePartitions <undefined> The advisory maximum number of post-shuffle partitions used in adaptive execution. This is used as the initial number of pre-shuffle partitions. By default it equals to spark.sql.shuffle.partitions. This configuration only has an effect when 'spark.sql.adaptive.enabled' and 'spark.sql.adaptive.shuffle.reducePostShufflePartitions.enabled' is enabled.
```
**Note**: Because there are so many configuration items that are exposed and require a lot of finishing, I will add the version numbers of these configuration items in another PR.
### Why are the changes needed?
Supplemental configuration version information.
### Does this PR introduce any user-facing change?
Yes
### How was this patch tested?
Exists UT
