Allow : in the source tag and add pinecone_test as a source tag for all integration tests (#137)

## Problem

Some customers have requested to allow : in the source tag field and for
all internal pinecone integration tests, add source tag as
pinecone_test.

## Solution

Allow : as a part of source tag and set pinecone_test as a source tag
for integration test
