Merge branch 'jk/push-config'

Restructure "git push" codepath to make it easier to add new
configuration bits and then add push.followTags configuration that
turns --follow-tags option on by default.

* jk/push-config:
  push: allow --follow-tags to be set by config push.followTags
  cmd_push: pass "flags" pointer to config callback
  cmd_push: set "atomic" bit directly
  git_push_config: drop cargo-culted wt_status pointer
