Log metrics outside sagemaker studio

**Is your feature request related to a problem? Please describe.**
Today we are using sagemaker notebook as development environment, and we like the sagemaker experiment concepts and try to use sagemaker experiments API to track our work.
We found most of the features we need works just fine without sagemaker studio except metrics.

**Describe the solution you'd like**
A consistent API experience with or without sagemaker studio.
When tracking metrics, it saves to trail component.

**Describe alternatives you've considered**
Configurable backend alternative to sagemaker studio, when it is not yet in GA.
