KAFKA-3355: Fix GetOffsetShell doesn't work with SASL enabled Kafka

[murong00]

As described in JIRA: KAFKA-3355, i fixed this issue for kafka 0.10.1.1 in production systems, hoping it may help users with this version.

HI @murong00 ,
I guess your PR is the same as #2891 !!

@ijuma Can we review this before removing old consumer code? or Are we going to remove GetOffsetShell?

[ijuma]

Yes, #2891 was submitted first, so let's try to get that in instead. Also it builds on public APIs instead of the Scala AdminClient.

[ijuma]

Actually #3051 is the one that builds on public APIs, but that requires a KIP. So, maybe it makes sense to go with #2891 first and then do #3051.

[ijuma]

Hmm, on second thought, we should probably go with a reduced version of #3051 since #2891 adds methods to the Scala AdminClient that we don't want to add.
