tls,crypto: revert recent cipher lists changes

Revert "disable RC4, add --cipher-list command line switch" and
"tls: make --enable-legacy-cipher-list=val less verbose"

This reverts commit f9291a94 and
b5737bb9

.

There is still some work to be done to guarantee secure defaults and a
smooth upgrade path for v0.12.x users. Before this work is finished, we
want to be able to release new versions of v0.12.x. So instead of
waiting for these changes to be ready to ship, revert them and integrate
them when they're ready to be shipped.
