Change the defaults of ka-clone and reorder things slightly

[lillialexis]

Summary:

I also added some "opposite" args in arg groups (e.g., --protect-master and --no-protect-master), which users can't use at the same time.

So, the defaults are now (currently):

Option               | Is Default?
---------------------+-----------
use ka email         | yes
protect master hooks | yes
branch name hook     | yes
lint commit msg hook | no
pre-push lint hook   | yes
git config linked    | yes
commit template      | yes

@csilvers are these defaults good? Do you think I should toggle any of them? This is what I landed on after I started the implementation.

Should I rename these args to be a little more consistent with each other and their function? I don't love how they currently are (e.g., --no-msg meaning "don't use the ka commit template" and --no-lint referring to the pre-push linter but not the commit-msg linter), but don't know who else may have hard-coded them as they currently are. (Or if it's worth doing.)

Issue: FEI-6001

Test plan:

• Run ka-clone with no args, sees that the defaults are what we are saying they are
• Run with conflicting arguments (e.g., --protect-master and --no-protect-master), and see that it errors
• Try running with all arguments that are opposite of the deep faults and see that they do what we expect them to do
