Cijoe

* `cij_reporter`: fixed rendering of elapsed wall-clock
* Updated qemu module to match new 'qemu' with OCSSD support in 'qemu-img'

* A myriad of cleanup and fixes

* Deprecated Python Libraries
- nvm.py incomplete Python interface for liblightnvm using CLI
- spdk.py testcases implemented for liblightnvm in Python, this is handled
better by the liblightnvm testcases themselves, hence deprecated

* Bumped version number
* Added 'clean' to release-script

* Added option to define testcases "inline" in testplan
- It used to rely on a specific testsuite file
- It now uses inline, when it is defined, testsuite otherwise
* Added testplan/testsuite alias
- To be used for briefly describing how a set of testcases relates to the
testplan
* Expanded usage examples
* Fixes to environment sourcing and lnvm module
* Fixed prefix to interactive shell

Test-Runner

* Changed `cij_runner` arguments to positional

Example environment definitions

* Expanded declarations of reference environment

Added this CHANGELOG, a bunch of style fixes and a couple of logic fixes, and
some functionality changes.

Shell Modules

* Renamed `get_fib_range` to `cij::get_fib_range`
* `get_exp_2_range` to `cij::get_exp_2_range`
* vdbench: prefixed vars with `VDBENCH_`

Tools

Changed `cij_reporter` it now takes the output path as positional argument
instead of optional named argument. E.g.:

bash
How it was
cij_reporter --output /path/to/output

How it is now
cij_reporter /path/to/output
