Add int and valid sequences to AttributeValue type (open-telemetry#368)

jakemalachowski · toumorokoshi · commit 983edc623811 · 2020-01-20T09:32:27.000-08:00
The OT Spec states one of the valid AttributeValue types are:

An array of primitive type values. The array MUST be homogeneous, i.e. it MUST NOT contain values of different types.

This change updates the AttributeValue type to include homogeneous sequences of str, bool, int, and float
