Task:Extend kvp open function to also support URLs

[kanjoe24]

Goal

Extend the suport of the open function to support URL's.

https://github.com/rdkcentral/ut-control/blob/develop/include/ut_kvp.h

Transform function from

ut_kvp_status_t ut_kvp_open(ut_kvp_instance_t *pInstance, char *fileName);

to

ut_kvp_status_t ut_kvp_open(ut_kvp_instance_t *pInstance, char *fileNameOrUrl);

if the filename is prefixed with https/http:// then it's a url
if it's not prefixed then assume it's a file
if it's prefixed with file:// then assume it's a file.

@KarthikeyanR470 , lets discuss this when you are available.

We need to achieve something like below:

bool is_url(const char *input) {
    if (input == NULL) {
        return false;
    }
    return (strncmp(input, "http://", 7) == 0 || strncmp(input, "https://", 8) == 0);
}

if (is_url(input)) {
        char yaml[512]; // adjust size as needed
        snprintf(yaml, sizeof(yaml), "include: \"%s\"\n", input);
        fy_document_build_from_string(NULL, (const char *)yaml, sizeof(yaml))
    } else {
       fy_document_build_from_file(NULL, fileName);
    }

You also need to extend the tests to validate that this works as expected.
