Change handling of spring.config.location so it replaces defaults

Browse Source 
Previously, spring.config.name was handled in such a way that its
value would replace the defaults. By constrast, spring.config.location
would add to the defaults.

Update the handling of spring.config.location so that it replaces the
defaults. This aligns its behaviour with spring.config.name. To allow
users to add additional locations a new property,
spring.config.additional-location, has been introduced. It behaves as
spring.config.location did prior to this change.

Config locations are searched in reverse order. By default, the configured locations are
`classpath:/,classpath:/config/,file:./,file:./config/`. The resulting search order is:
`classpath:/,classpath:/config/,file:./,file:./config/`. The resulting search order is the
following:
. `file:./config/`
. `file:./`
. `classpath:/config/`

When custom config locations are configured, they are used in addition to the default
locations. Custom locations are searched before the default locations. For example, if
custom locations of `classpath:/custom-config/,file:./custom-config/` are configured, the

Alternatively, when custom config locations are configured using

Additional locations are search before the default locations. For example, if
