Subject: [PATCH] Add dependency for tsa_enabled flag before populating peer
 config and bringing up BGP (#18556)

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.
