* feat: Change signature of the Region::alter method
* refactor: Add builders for ColumnsMetadata and ColumnFamiliesMetadata
* feat: Support altering the region metadata
Altering the region metadata is done in a copy-write fashion:
1. Convert the `RegionMetadata` into `RegionDescriptor` which is more
convenient to mutate
2. Apply the `AlterOperation` to the `RegionDescriptor`. This would
mutate the descriptor in-place
3. Create a `RegionMetadataBuilder` from the descriptor, bump the
version and then build the new metadata
* feat: Implement altering table using the new Region::alter api

Region id is cheaper to clone than name

* refactor: Move dedup func to individual mod
* chore: Update ListValueRef comments
* refactor: Move replicate to VectorOp
Move compute operations to VectorOp trait and acts as an super trait of
Vector. So we could later put dedup/filter methods to VectorOp trait,
avoid to define too many methods in Vector trait.
* refactor: Move scalar bounds to PrimitiveElement
Move Scalar and ScalarRef trait bounds to PrimitiveElement, so for each
native type which implements PrimitiveElement, its PrimitiveVector
always implements ScalarVector, so we could use it as ScalarVector
without adding additional trait bounds
* refactor: Move dedup to VectorOp
Remove compute mod and move dedup logic to operations::dedup
* feat: Implement VectorOp::filter

* feat: rebase develop and change timestamp/gmt_crated/gmt_modified type to timestamp
* refactor: use assert_eq instread of assert
* doc: fix comment in Script#execute function
LogicalTypeId to ConcreteDataType is only allowed in tests, since some
additional info is not stored in LogicalTypeId now. It is just an id, or
kind, not contains full type info.
* test: Fix merge tests
The merge tests still use Int64Vector for timestamp, which should
use TimestampVector instead.
* test: Test Debug format for Source::Reader
Mainly for improve code coverage
* wip: impl timestamp data type
* add timestamp vectors
* adapt to recent changes to vector module
* fix all unit test

* fix: Fix MockChunkReader never stop
* feat: Impl cmp_element() for Vector
* chore: Add doc comments to MutableVector
* feat: Add create_mutable() to DataType
Add `create_mutable()` to create a MutableVector for each DataType.
Implement ListVectorBuilder and NullVectorBuilder for ListType and
NullType.
* feat: Add ValueRef
ValueRef is a reference to value, could be used to avoid some allocation
when getting data from Vector. To support ValueRef, also implement a
ListValueRef for ListValue, but comparision of ListValueRef still
requires some allocation, due to the complexity of ListValue and
ListVector.
Impl some From trait for ValueRef
* feat: Implement get_ref for Vector
* feat: Remove cmp_element from Vector
`cmp_element` could be replaced by `get_ref` and then compare
* feat: Implement push/extend for PrimitiveVectorBuilder
Implement push_value_ref() and extend_slice_of() for
PrimitiveVectorBuilder.
Also refactor the DataTypeBuilder trait for
primitive types to PrimitiveElement trait, adds necessary cast helper
methods to it.
- Cast a reference to Vector to reference arrow's primitive array
- Cast a ValueRef to primitive type
- Also make PrimitiveElement super trait of Primitive
* feat: Implement push/extend for all vector builders
Implement push_value_ref() and extend_slice_of() for remaining vector
builders. Add some helpful cast method to ValueRef and a method to
cast Value to ValueRef.
Change the behavior of PrimitiveElement::cast_xxx to panic when unable
to cast, since push_value_ref() and extend_slice_of() always panic
when given invalid input data type.
* feat: MutableVector returns error if data type unmatch
* test: Add tests for ValueRef
* feat: Add tests for Vector::get_ref
* feat: NullVector returns error if data type unmatch
* test: Add tests for vector builders
* fix: Fix compile error in python coprocessor
* refactor: Add lifetime param to IntoValueRef
The Primitive trait just use the `IntoValueRef<'static>` bound. Also
rename create_mutable to create_mutable_vector.
* chore: Address CR comments
* feat: Customize PartialOrd/Ord for Value/ValueRef
Panics if values/refs have different data type
* style: Fix clippy
* refactor: Use macro to generate body of ValueRef::as_xxx
* feat: implement alter table
* Currently we have no plans to support altering the primary keys (maybe never), so removed the related codes.
* make `alter` a trait function in table
* address other CR comments
* cleanup
* rebase develop
* resolve code review comments
