Review Comment:
1.The reason why I want to create a new `CatalogMgr` is because the
`CatalogMgr` needs a timing refresh time, because when the `CatalogMgr` of
`Env` is initialized, there is no such timing refresh time, in order to reuse I
will subsequently use the `CatalogMgr` of `Env` and assign this refresh time to
the` CatalogMg`r of `Env` when it is initialized and constructed
2.Ok,I will move the "refresh catalog method" from `CatalogMgr` to
`RefreshMgr` and putthe refresh timer thread in `RefreshMgr`
3.Ok, I will not change other lines of code
