Please add a note that without tx/rx interval in the DB, BFD session will use the default timers BFD_SESSION_DEFAULT_TX_INTERVAL and BFD_SESSION_DEFAULT_RX_INTERVAL

This check will be added later, right?

Please include sonic-mgmt tests with Rx/Tx timer to check if these are supported by vendor SAI for BFD hardware offload.

ill add those tests after I have made the changes for directly connected nexthops.

What I did
This change add support for
rx_monitor_timer
tx_monitor_timer
check_directly_connected
Why I did it
This change is beneficial because it adds support for BFD Tx, Rx interval for Vnet Monitored routes as required by DASH project.
How I verified it
Added a unit test to verify the functionality.
Details if related
The Tx and Rx values are added on per-route basis. Therefore the same values are used for each nexthop. if the user needs to se different values for each next hop then they can add the values and nexthops incrementally.
e.g.
The user can also update these values by selectively removing and readding a nexthop with different Tx and Rx values.
