FWIW fedora-review only requires yum-utils and that's only for
repoquery. Based on a quick glance at dnf repoquery module there are a
few things missing that we are using with repoquery:
 * -C (use cache only)
 * --resolve (resolves to packages that provide required symbols)

We also run 'yum makecache' so before all actual repoquery commands (that's
why we then use cache). This might not be needed with dnf since it
usually caches yum metadata and doesn't redownload on every query.

Dnf repoquery also behaves differently than yum-utils repoquery. For
example:
$ repoquery --requires python
libc.so.6(GLIBC_2.0)
libdl.so.2
libm.so.6
libpthread.so.0
libpython2.7.so.1.0
libutil.so.1
python-libs(x86-32) = 2.7.5-14.fc20
rtld(GNU_HASH)
libc.so.6(GLIBC_2.2.5)(64bit)
libdl.so.2()(64bit)
libm.so.6()(64bit)
libpthread.so.0()(64bit)
libpython2.7.so.1.0()(64bit)
libutil.so.1()(64bit)
python-libs(x86-64) = 2.7.5-14.fc20
rtld(GNU_HASH)

$ dnf repoquery --requires python
rtld(GNU_HASH)
libm.so.6
libpthread.so.0
libdl.so.2
libutil.so.1
libpython2.7.so.1.0
libc.so.6(GLIBC_2.0)
python-libs(x86-32) = 2.7.5-9.fc20
rtld(GNU_HASH)
libm.so.6()(64bit)
libpthread.so.0()(64bit)
libdl.so.2()(64bit)
libc.so.6(GLIBC_2.2.5)(64bit)
libpython2.7.so.1.0()(64bit)
libutil.so.1()(64bit)
python-libs(x86-64) = 2.7.5-9.fc20
rtld(GNU_HASH)
libm.so.6
libpthread.so.0
libdl.so.2
libutil.so.1
libpython2.7.so.1.0
libc.so.6(GLIBC_2.0)
python-libs(x86-32) = 2.7.5-14.fc20
rtld(GNU_HASH)
libm.so.6()(64bit)
libpthread.so.0()(64bit)
libdl.so.2()(64bit)
libc.so.6(GLIBC_2.2.5)(64bit)
libutil.so.1()(64bit)
libpython2.7.so.1.0()(64bit)
python-libs(x86-64) = 2.7.5-14.fc20

No idea why it's this way though.
