Error when GetShardIterator by timestamp

[lisashizhu]

When calling GetShardIterator by timestamp, it is struck and times out so that we could not get http response.

Version used:

v3.1.0 --> kinesalite
v2.0 --> .net standard
v3.3.100.80 --> AWSSDK.Kinesis

Reproduce steps

1. Build Docker image

FROM instructure/node:10
MAINTAINER Instructure

ENV DATADIR /var/lib/kinesalite

USER root
RUN mkdir $DATADIR && chown docker:docker $DATADIR
USER docker

RUN npm install kinesalite@3.1.0

EXPOSE 4567
VOLUME $DATADIR

ENTRYPOINT ["/tini", "--", "/usr/src/app/node_modules/kinesalite/cli.js", "--path", "/var/lib/kinesalite"]

2. Deploy and run it in Docker
3. Use kinesis consumer written by .net standard to call Kinesis service. AWS Document:https://docs.aws.amazon.com/sdkfornet/v3/apidocs/
Code reference : https://sachabarbs.wordpress.com/2018/09/17/aws-kinesis/
(please refer Consumer Data Streams API part)
3.1 call DescribeStreamAsync
3.2 call GetShardIteratorAsync with timestamp --> ERROR

Expected result

By the time GetShardIteratorAsync is called with timestamp there is no stream yet in Kinesis service. However it should still return shard iterator without any records inside.

Actual result

When calling GetShardIterator by timestamp, it is struck and times out(after around 1 min,) so we could not get http response.
