Feat : Add stored procedure

[elrhomariyounes]

What kind of change does this PR introduce?

Hello, I implemented a method to make stored procedure call

What is the current behavior?

26

What is the new behavior?

• Call a stored procedure

Usage

            var parameters = new Dictionary<string, object>()
            {
                { "p1", "v1" },
                { "p2", "v2" }
            };
            var response = await client.Rpc("procedure_name", parameters);

@elrhomariyounes succinct! I think to keep things DRY we should refactor and move PrepareRequestHeaders to a Static function on Helpers

class Table {
  public Dictionary<string, string>PrepareRequestHeaders(Dictionary<string, string> headers = null) {
     // ...
  }
}

to

class Helpers {
   public static Dictionary<string, string> PrepareRequestHeaders(Dictionary<string, string> headers = null, ClientAuthorization authorization = null, ClientOptions options = null) {
    // ...
  }
}

Then use the new function there to setup the Authentication call that Rpc is doing.

Thoughts?
