chore: upgrade peer/dev deps to @opentelemetry 0.14.0

[aabmass]

Fixes #215

Upgrading peer/dev deps and fixing the associated breaking changes from upstream. Mainly:

• Propagator getters and setters were changed into classes and renamed
• ExportResult was changed into an object with separate code and error fields
• ExportResult enum is now ExportResultCode and FAILED_RETRYABLE was removed.
  • retries were never actually implemented, so this is not a functionality change
  • they decided retries should be implemented by the exporters directly, which makes sense. Tracked in Handle retry logic and error logging internally #181
• Meter.getBatcher() -> Meter.getProcessor()
• CanonicalCode -> StatusCode
• Propagators have a new fields() method (see spec).

Tested the new packages manually as well, everything is working great.

not sure if anyone's aware of it, but using the current stable version (0.7.0) with opentelemetry 0.13.0 causes a torrent of errors like this:

TypeError: Cannot read property 'FAILED_RETRYABLE' of undefined
at TraceExporter._batchWriteSpans (/app/node_modules/@google-cloud/opentelemetry-cloud-trace-exporter/build/src/trace.js:91:40)

@electricmonk yes, this PR is the fix. The peerDependencies in each package are correct and things should be working as long as they are satisfied:

opentelemetry-operations-js/packages/opentelemetry-cloud-trace-exporter/package.json

Lines 65 to 68 in facb8e0

	"@opentelemetry/api": "^0.12.0",
	"@opentelemetry/core": "^0.12.0",
	"@opentelemetry/resources": "^0.12.0",

ETA for release? current latest is not working (as you are all aware)

@aabmass note that open telemetry 0.14 was recently released.
