Missing some response header in Map<String,String>

[sepbehroozi]

In response header sometimes we have multiple headers with same name like Set-Cookie:
In com.android.volley.toolbox.BasicNetwork.java file last static method called convertHeaders(Header[] headers) that returns a Map<String,String>.
We should use another data structure instead of Map<String,String> for handle headers with the same name conflict

Responses may have multiple separated Set-Cookie: names in header like this :
