Feature request: allow BaseProvider in Parameters to not have a client

[dreamorosi]

Use case

When creating a custom Parameters provider I should be able to seamless set my own backend, regardless of whether this might be AWS, a 3rd party, or anything else.

Currently the BaseProvider expects a constructor parameter called proto (as-in prototype, bad name) that you're supposed to pass and that will be used whenever you are not passing an AWS SDK client.

This implementation is too tightly coupled with the notion that BaseProvider expects to be extended by a provider that relies on an AWS SDK client. This is not always the case, and as a customer implementing my own provider I should not have to work around this limitation.

Solution/User Experience

For end customers using the Parameters utility as-is, the experience should stay the same.

For those other customers who implement their own provider, the implementation should be simpler and not require to pass a class prototype to be instantiated as client.

Acknowledgment

• This feature request meets Powertools for AWS Lambda (TypeScript) Tenets
• Should this be considered in other Powertools for AWS Lambda languages? i.e. Python, Java, and .NET
