Implement temporality conversion #2329
Description
Blocked by #2327
Temporality conversion is specified in the design doc. For this issue:
- Create a component to handle temporality conversion and storing of previous collection interval's cumulative point value when necessary. For example, there is no need to store previous cumulative for async instruments and cumulative export temporality.
- Write temporality conversion algorithm. Use the export format added for Create dataclasses for metric exporter batch #2327 as the input and output of the algorithm
