Start HUP signal handler earlier
Start HUP signal handler earlier

When prometheus starts up and is recovering its state it will not handle
SIGHUPs. If it receives those during this phase it will exit. The change
here makes prometheus ignore SIGHUPs until it is ready to handle them.

Note this is only done for SIGHUP because that signal is used for
trigger a config reload and a such something could already be sending
these signals as part of a config update.
