feat: add support for debug and storage config

[ynyany]

Issue #, if available:

1. The default configuration for builder instance's storage is gp2 with 8GB, this is quiet useless in practical use case where it very likely to used up all spaced e.g ``` no space left on device

   
   thus introducing a configuration default 128GB as storage option

2. The builder instance is not accessible in case failure made it very hard to debug, thus introduce debug option
