KIP: https://cwiki.apache.org/confluence/display/KAFKA/KIP-546%3A+Add+Client+Quota+APIs+to+the+Admin+Client

API docs:
https://kafka.apache.org/protocol#The_Messages_DescribeClientQuotas

https://kafka.apache.org/protocol#The_Messages_AlterClientQuotas

I followed a similar code style to what was used for alterconfigs. Let me know if there is a better code style to use for this.

If this PR is too large to review I could split it into three pieces:

  1. Adding support for float64 data types used in Kafka's protocol (quotas appear to be the only APIs that use this data type)
  2. Add createquotas APIs
  3. Add describequotas APIs

entries := make([]alterclientquotas.Entry, len(req.Entries))

for entryIdx, entry := range req.Entries {
entities := make([]alterclientquotas.Entity, len(entry.Entities))

I followed the pattern used elsewhere where we choose not to reuse the types defined in the protocol package and create new types in the kafka package

responseEntries[responseEntryIdx] = AlterClientQuotaResponseQuotas{
ErrorCode: responseEntry.ErrorCode,

It looked like elsewhere we created a new errors map field in the return and grouped all the errors there instead of keeping them nested under the individual entries. Do we want that instead of what I have here?

Is there a word missing at the end there ("false" maybe)?

Most of these doc strings (including this one) are just quotes from the API docs. This verbiage seems common in the Kafka API docs so I think it is ok. I can change it if you feel otherwise

client, shutdown := newLocalClient()
defer shutdown()

expectedAlterResp := AlterClientQuotasResponse{

Maybe it's the standard practice to define the expected value early but it feels more logical to me just before the assert (and after the err check)

You're right, I just made this change.

It looks like v1 is compact and nullable.

I believe these types also need to be marked with a tag field for v1.

@rhansen2 thanks for the review! I added tags to those types as well as similar ones in alterclientquotas
