key_generator: fix timing, make tests more robust
previously there was an edge case in the timing of expected behaviour
of the key_generator (w.r.t. the refresh delay and twisted/foolscap
delivery). if it took >6s for a key to be generated, then it was
possible for the pool refresh delay to transpire _during_ the
synchronous creation of a key in remote_get_rsa_key_pair. this could
lead to the timer elapsing during key creation and hence the pool
being refilled before control returned to the client.
this change ensures that the time window from a get key request
until the key gen reactor blocks to refill the pool is the time
since a request was answered, not since a request was asked.
this causes the behaviour to match expectations, as embodied in
test_keygen, even if the delay window is dropped to 0.1s

it adds a tahoe create-key-generator command which initialises an
empty dir with a tahoe-key-generator.tac file which can then be run
via twistd. it stashes its .pem and portnum for furl stability and
writes the furl of the key gen service to key_generator.furl, also
printing it to stdout.

fix check-memory to use new upload API (which requires a "convergence" argument), and change it to measure convergence instead of random-key, since convergence is the use case we care about more

use added secret to protect convergent encryption
Now upload or encode methods take a required argument named "convergence" which can be either None, indicating no convergent encryption at all, or a string, which is the "added secret" to be mixed in to the content hash key. If you want traditional convergent encryption behavior, set the added secret to be the empty string.
This patch also renames "content hash key" to "convergent encryption" in a argument names and variable names. (A different and larger renaming is needed in order to clarify that Tahoe supports immutable files which are not encrypted content-hash-key a.k.a. convergent encryption.)
This patch also changes a few unit tests to use non-convergent encryption, because it doesn't matter for what they are testing and non-convergent encryption is slightly faster.
