Apollo不同表的的相同业务含义的字段长度不一致

你的特性请求和某个问题有关吗？请描述

在实际使用时，发现日志经常会有少量的数据库字段超长的报错，发现是Release表的NamespaceName字段是 varchar(500)，但是InstanceConfig表的ConfigNamespaceName字段是 varchar(32)

1. 比如NamespaceName，在AppNamespace表中Name 字段是varchar(32)
2. 比如Cluster字段，Cluster表中Name字段是 varchar(32)，Commit表中ClusterName字段是 varchar(500)

相同含义的字段在所有表中是否有必要同一，避免一些潜在的问题

I saw that there was a PR #4725 that made some optimizations for the field length unification, but it did not include the three tables commit, namespace, and release. Why is this?

[nobodyiam]

It includes the commit, namespace, and release tables but appears to miss the NamespaceName and ClusterName fields.

I think this can be fixed and is safe.
