Motivation:
For example,
DefaultHttp2Headers headers = new DefaultHttp2Headers();
headers.add("key1", "value1");
headers.add("key1", "value2");
headers.add("key1", "value3");
headers.add("key2", "value4");
produces:
DefaultHttp2Headers[key1: value1key1: value2key1: value3, key2: value4]
while correctly it should be
DefaultHttp2Headers[key1: value1, key1: value2, key1: value3, key2: value4]
Modifications:
Change the toString() method to produce the beforementioned output.
Result:
toString() format is correct also for keys with multiple values.
