Enable File-based VCAP_SERVICES Support

[AdityaSahSAP]

Description

Due to platform limitations in BTP, the size of the VCAP_SERVICES environment variable is now strictly limited to 130 KB. This limitation cannot be overridden by applications. To handle this situation, the platform team has introduced support for file-based VCAP_SERVICES via the VCAP_SERVICES_FILE_PATH environment variable, which points to a file containing the full VCAP JSON payload.

Currently, your library only reads service bindings from the VCAP_SERVICES environment variable. This prevents applications from accessing service bindings when the environment variable exceeds the size limit and the platform provides the data via a file.

Request

Please enhance the library to support reading the VCAP_SERVICES payload from a file, using the path specified in the VCAP_SERVICES_FILE_PATH environment variable, as a fallback when VCAP_SERVICES is not set. This will ensure compatibility with the new platform behavior and allow applications to function correctly regardless of the VCAP_SERVICES size.

I saw a similar issue already being addressed : #362
Hence closing this one

Thanks for raising the issue. It is a duplicate to #362 which is resolved by #363.
