Update `ConfigData` so that it signal if is considered optional. This
update allows `ConfigDataLocationResolvers` to return results that
behave in the same way as `optional:` prefixed locations without the
user themselves needing to prefix the location string.

Update `ManagementWebSecurityAutoConfiguration` so that the
`managementSecurityFilterChain` bean has an explicit order.

Prior to this commit, the `managementSecurityFilterChain` would override
the `securityFilterChain` in `RemoteDevtoolsSecurityConfiguration` which
would prevent the remote devtools endpoint from being accessed.

Update `StandardConfigDataLocationResolver` to deal with patterns when
resolving empty directories. This update also fixes the handling of
mandatory pattern locations which would previously throw an exception.

The error message returned when a location with a pattern does not
contain any subdirectories has also been improved.
