Evaluating url function at time of DB connection

[fmasa]

First of all, thank you for awesome plugin. It makes my life significantly better.

I am resolving database url dynamically for multiple databases using CLI command that generates temporary credentials as follows:

vim.g.dbs = vim.tbl_map(
  function(database)
    return {
      name = database,
      url = function()
        return vim.fn.system('<command obtaining connection string>')
      end
    }
  end,
  staging_databases
)

The problem is that when I open DBUI, the url is resolved for all the databases. Since our company has 20+ databases and generating credentials takes few seconds, this takes a long time to just open UI.

Would it be possible to defer url resolution until actual connection to the database?
