Track accounts using wildcards

[RuneStone0]

I'd like to run a full node, with full account history, but only for a selected number of accounts (hundreds). Using the --track-account option is not feasible because the accounts to track will constantly change (new users added). Restarting the full node with a new list of accounts to track is a bad solution. As far as I know its not possible to change the full node config during run-time either.

I suggest that the config parameter --track-accounts will support wildcards so the following can be specified instead: --track-accounts=myusers-*,myotherusers-*,*identifier*

Alternative solution could also work, but is less flexible in my opinion:
