feat: Generator Configuration

[tusharmath]

This feature essentially allows developers to create GraphQL configurations automatically. This is done by providing a few inputs to the "ConfigGenerator" and then a new Configuration is automatically generated.

Technical Requirements

1. Here is sample CLI integration of this feature:

   tailcall generate ./generator.json

2. Proposed Configuration Input

   enum Operation {
       Query,
       Mutation
   }
   
   struct Input {
       source: Source,
       field_name: String,
       operation: Option<Operation>,    
   }
   
   enum Source {
       URL {
           url: String, 
           headers: Option<BTreeMap<String, String>>,        
           method: Option<Method>, 
           body: Option<serde_json::Value>
       },
       Proto {path: String},
       Config {url: String}
   }
   
   enum Transformer {
       TypeMerger {threshold: Option<f32>},
       AmbiguousType {
           input: Option<Name>,
           output: Option<Name>
       },
       ConsolidateBaseURL {threshold: Option<f32>},
       BetterTypeName,
       TreeShake
   }
   
   struct Name {
       prefix: Option<String>,
       postfix: Option<String>
   }
   
   struct Config {
       inputs: Vec<Input>,
       transformers: Vec<Transformer>,
       output: Output,
       schema: {
           query: Option<String>,
           mutation: Option<String>
       } 
   }
   
   struct Output {
       path: String,
       format: Option<Format>
   }
   
   enum Format {
       GraphQL,
       JSON,
       YAML
   }
