[autotest] Add server database to django model.
Server database is added to store information about servers running in an
Autotest instance. This is the first CL to implement it. Design doc:
go/chromeos-lab-serverdb-design
django model uses db_router to rout database calls to different database
connections:
local: All AFE table calls.
global: All TKO table calls.
readonly: Calls from web frontend.
This CL adds another router for all calls to server database to `server`.
DEPLOY=migrate_server_db
CQ-DEPEND=CL:230814
BUG=chromium:424778
TEST=unitest, part of the test is done by atest code that'll be in another cl.
Test server database migration:
./database/migrate.py sync 0 -d AUTOTEST_SERVER_DB
./database/migrate.py sync 1 -d AUTOTEST_SERVER_DB
./database/migrate.py sync 2 -d AUTOTEST_SERVER_DB
./database/migrate.py sync 3 -d AUTOTEST_SERVER_DB
python frontend/health/utils_unittest.py
