Allow only user specified dap_configurations as options

[angles-n-daemons]

Hi there,

First off, thanks for the library. It's been really helpful as a developer who enjoys using vim.

Chiming in today to say that I find all of the common_debug_configs a bit cumbersome. Not only because they all show up as options when debugging, but also because they appear higher in the list than user specified configurations.

Are you open to the idea of hiding the common options? Something to the effect of a configuration value hide_default_configs or something, or even show_common_configs which defaults to true? I'm happy to take a crack at it if it's something you think could be useful.

Desired:

you can override it

        dap.configurations.go = {}

I suppose if I use a launch.json file, it's not exactly straightforward how to patch my options into the prompt.

For example, in my nvim-dap-go configuration I have the following:

      require('dap-go').setup {}
      require('dap').configurations.go = {}

Where the default options are still inserted in.

Have a look at my config, it has no such issue
