* In the switch case, change the labels as well as the pack functions:
* `pack_dl_config_request` becomes `pack_dl_tti_request` [x]
* `pack_ul_config_request` becomes `pack_ul_tti_request` [x]

* `pack_hi_dci0_request` becomes `pack_ul_dci_request` [x]

### Task-B [unpacking]
* Modify `nfapi_p7_message_unpack()` in `nfapi_p7.c`
* `unpack_dl_tti_request` [x]
* `unpack_ul_tti_request` [x]
* `unpack_ul_dci_request`
* `unpack_ul_dci_request` [x]
* `unpack_tx_data_request` [x]
* Similarly change all the `unpack` functions within the switch-case block.

* `pnf_handle_ul_tti_request`
* `pnf_handle_ul_dci_request`
* `pnf_handle_tx_data_request`
to handle DL P7 messages at pnf
### Task-C
* Write the `ul_tti` alternative for `nfapi_vnf_p7_ul_config_req()` in `vnf_p7_interface.c` and other such functions.
* `dl_tti` is present as `nr_dl_config` [x]

* Resolve the hard-coded areas in source code. [`HIGH-PRIORITY`] [x]
* Write the `ul_tti` equivalent for `oai_nfapi_dl_config_req` in `nfapi_vnf.c` and other such functions.
