This patch removes most sys.exits() from installer modules and
scripts and
replaces them with ScriptError. I only left sys.exits at places
where the user
decides yes/no on continuation of the script.
I wonder if yes/no should be replaced with KeyboardInterrupt or some
exception, too...

I'm not sure, it seems more clear to just really exit if the user
desires it
and it's what we say we'll do (with possible cleanup beforehand). Do
you think
we could benefit somehow by raising an exception here?
I'm just thinking out loud.

It seemed to me that it is easier to share cleanup on one except block
of having if (interrupt): cleanup; if (interrupt2): same_cleanup;


Again, just wondering out loud.

If the cleanup is the same, or similar it might be more beneficial to
have it in a function where you could pass what was set up already and
therefore needs cleanup. But that's just an opinion coming from thinking
out loud as well. I went through the code to see if there's much cleanup
after these user actions and it seems that usually there's nothing much
if anything. However, thinking in advance may save us much trouble in
the future, of course.

Btw the original scope of the ticket is to replace sys.exit calls ONLY
in installer modules. Please don't waste time with debugging other use
cases before 4.4 is out.

I might have gotten carried away a bit. Would you suggest keeping the sys.exits replaced only in ipaserver/install/server/replicainstall.py, ipaserver/install/server/install.py modules which are the installer modules managed by AdminTool? I considered the modules in ipaserver/install/ to also be installer modules as they are heavily used during installation and the sys.exits there mainly occur in functions called from install()/install_check() methods. The *-install scripts were perhaps really obviously over the scope.

I'll keep the sys.exit replaces that won't make it here on the side, we may want to do them later.
