Add option for preserving symlinks for `aws deploy push` command

### Describe the feature

The feature would add a `--preserve-symlinks` option to the `aws deploy push` command. By default, symlinks are materialized into their targets when they are zipped for deploy. Some applications, e.g. PHP's Doctrine ORM vendor/bin scripts, rely on symlinks to be preserved to work, and are thus broken by the default deploy behavior if your PHP project's deployment archive includes its vendor directory (which it should).

A corresponding `--no-preserve-symlinks` option would also be added as part of the feature.

### Use Case

Some applications, e.g. PHP's Doctrine ORM vendor/bin scripts, rely on symlinks to be preserved to work, and are thus broken by the default deploy behavior if your PHP project's deployment archive includes its vendor directory (which it should).
