Brief change log

Summary:

  1. Add paimon lake table DDL support and related UT which learned from LakeEnabledTableCreateITCase, when other lake table format were added, modular refactoring will be needed cause LakeStoragePlugin was loaded by SPI.
  2. Support alter table with only set properties, left TODO for more support.

@Yohahaha I highly recommend splitting this PR into two:

  • one is to support alter table, which can support the TableChange type as much as possible.
  • another is to verify metadata for tables which enable datalake. If possible, try to extend SparkCatalogTest.
