fix: atom and process leaks (#47)

* fix: atom and process leaks

Previously, the channel name would use `list_to_atom(pid_to_list(self()))`, which leads to
an atom leak.

Not only that, but the `greptime_worker` `gen_server` process did not set `trap_exit` to
true, which means that the `terminate` callback was not called, leaking `grpcbox_channel`
processes.
