Reduce Package Size / Split package by using extras

[DanielHabenicht]

Describe the feature

It would be great if the services available via the boto3 package could be selected individually to minimize the installment size.

Use Case

To optimize the size of a docker image I had a look at the packages installed and boto3 came out on top:

Proposed Solution

It would be great if similar to the Common runtime feature (boto3[crt]) every service could be selected on its own. For example:

1. Installing boto3 without the need for optimization:
   pip install boto3[full] (Installment size: 82 MB*)
2. Installing boto3 without the need for optimization and with the Common runtime feature:
   pip install boto3[full,crt]
3. Installing only the s3 service:
   pip install boto3[s3] (Installment size: 1,4 MB*)
4. Installing multiple services:
   pip install boto3[s3,ec2,iot] (Installment size: 15,3 MB*)

Every feature would only include the data folder that currently resides in the botocore package and the botocore package would only contain the code that holds it all together.

* Installment Size just for illustration

Other Information

That's a great way to save everybody some resources! Especially with such a widely used image.

Sorry got mixed up with the packages, this is a duplicate of boto/botocore#1543
