This ensures any incoming profile connection will be blocked if its UUID
is not allowed by the following assumption:
1. Each system profile asks adapter authorization when seeing a incoming
connection.
2. Each external profile checks if its UUID is allowed by adapter when
seeing a incoming connection.

The following test steps were performed after enabling admin plugin:
1. Set ServiceAllowList to ["1234"].
2. Turn on a paired classic keyboard. Verify it can not be connected.
3. Set ServiceAllowList to
["1800","1801","180A","180F","1812"]
4. Turn off and turn on the keyboard. Verift it can be connected.
