Why I did it

Ensure BGP peer bring-up and route advertisements are done only after checking TSA status during reload

Work item tracking

• Microsoft ADO (number only): 27171112

How I did it

Add dependency on tsa_enabled flag before peer configuration

How to verify it

• Validate that the BGP session bring up is not complete until tsa_enabled flag is populated.
• Ensure no traffic is drawn to the device when in TSA and reboot with BGP unshut.

Hi @tjchadaga is there a known issue for this one? like routes are advertised out with TSA enabled on a reload? I'm asking this because 202305 piloting is almost done, should I hold the pilot for this one?
