Madhura Bhave a8592f36d4 Add prefix support for property source
We configure the `SystemEnvironmentPropertySource` as a `Prefixed` property
source. When adapting this to a `ConfigurationPropertySource, a
`PrefixedConfigurationPropertySource` will be created for it.
A `PrefixedConfigurationPropertySource` will resolve property
such as `foo.bar` to `my.foo.bar` for a prefix of `my`.
