Break out install into more steps, add -key_algorithm to pkisilent

Installing dogtag is quite slow and it isn't always clear that things
are working. This breaks out some restart calls into separate steps
to show some amount of progress. There are still some steps that take
more than a minute (pkicreate and pkisilent).

Add new argument to pkisilent, -key_algorithm

Update a bunch of minimum required versions in the spec file.
