Update to Proto v0.5.0 (#1588)

* chore: updating submodule for opentelemetry-proto

* chore: necessary changes after upgrade to proto ver. 0.5.0, aligning metrics to latest spec changes

* chore: removing examples from lerna bootstrap

* chore: cleaning ups unused interfaces

* chore: fixing unit test

* chore: updating aggregation temporality rules

* chore: updating temporality for value recorder

* chore: removing unneeded lib

* chore: span id and trace id as hex

* chore: adding value recorder to example
