[Design]: SQL Database flow has ImportFrom sub-flow which does not have clear flow end stage

here is the sample from CR:
```
var dbFromImport = sqlServer.Databases
.Define("db-from-import1")
.DefineElasticPool("epi")
.WithStandardPool()
.Attach()
.ImportFrom(storageAccount, "from-sample", "dbfromsample.bacpac")
.WithSqlAdministratorLoginAndPassword(administratorLogin, administratorPassword)
.Create();
```

I think it would be better to have define.....Apply/Attach flow instead of ImportFrom which I read as a single statement and then the next line `WithSqlAdministratorLoginAndPassword` for me is related to database definition and not to Import configuration.
