@siddharthaturbot the changes look good but I have left a few minor suggestions.

The following changes need to be made across all the tables in the PR:

• We typically follow the format plugin.Logger(ctx).Error("<table_name>.<function_name>", "query_error/connection_error", err) while adding trace logs to the tables. You might choose to add additional details wherever you feel necessary 👍.
• Were you able to test response, err := plugin.RetryHydrate(ctx, d, h, getDetails, &plugin.RetryConfig{ShouldRetryError: shouldRetryError})? and does it work as per the expectation?

Should we also add a separate section highlighting the optional quals for this table as mentioned in https://github.com/turbot/steampipe-plugin-steampipecloud/pull/31/files#diff-1d6098679bced8287cde2de661f16aa150ee4a1566f349ad70b0206a00ad6c2bR27-R38

we dont support optional quals in this table yet. The same has been added to the steampipecloud_workspace_process since that table supports it.

also for the second point - I have tested the retryhydrate stuff and it works as expected.
