  1. [test] Enable passing arguments to the functest harness 

    Move the required args to the end and name them the "test commands."
Pass the test commands via an environment variable, and place them at
the end of the invocation.

This makes the test commands unable to be overridden by test_arg
arguments, and simultaneously, it allows the user to specify test_arg
arguments on the bazel command line to modify arguments to opentitantool
and friends. Those test_arg arguments can override or supplement the
test harness's arguments provided by the bazel rule.

  2. [cryptolib] csrng driver 

    This commit introduces the a driver for the software instance of the
csrng. The driver interface supports regular DRBG functions, i.e.
instantiate, reseed, update and generate functions.

The focus of this commit is functionality, so there are a few things
that will be addressed in future commits:

- Handling of blocking operations. This is currently an area where we
  need to come up with a strategy for the crypto library as indefinite
  blocking operations may need an unconditional timeout when called in
  higher application layers.
- alert and state checks.
