  -Dchangelist=$(git tag -l --sort=creatordate | tail -n 1).patch2.1.$(git rev-list --count HEAD).$(date +%Y%m%d-%H%M%S)

1. Add option to select a custom AWS S3 Storage Class for uploaded objects:
- STANDARD (default)
- STANDARD_IA

Note:
 a) SUPPORTED ONLY by AWS CLI mode.
 Selected custom Storage Class is supported by AWS CLI mode only!

 b) NOT SUPPORTED by AWS API mode.
 Default AWS API mode ignores any selected custom AWS S3 Storage Class -
 it will always upload filed with STANDARD Storage Class.

2. Updated Readme with build and test notes.

3.Add Maven property patch.version

Notes:
- Jenkins (2.443) or higher required
- Build with skip test and Maven option -Dchangelist=plugin-version
For example:

 mvn clean package -DskipTests \
 -Dchangelist=$(git tag -l --sort=creatordate | tail -n 1).patch2.2.$(git rev-list --count HEAD).$(date +%Y%m%d-%H%M%S)

Or with patch.version:

 mvn clean package -DskipTests \
 -Dchangelist=$(git rev-parse --abbrev-ref HEAD)_v\${patch.version}-$( \
 git rev-list --count HEAD).$(git rev-parse --short HEAD)$(git diff --quiet || echo  .diff).$(date +%Y%m%d-%H%M%S
