Python has a high startup cost, so go back to invoking it only once per
server start, rather than once per client start. This is a measurable
performance improvement (running time ~*0.5 with PSK, less dramatic with
asymmetric crypto).

With this commit, translate_ciphers.py would be based on standard
cipher suite names instead of MbedTLS naming convention.

The list was trimmed previously according to code coverage, however
this did not really evalute all test cases, e.g in the case of re.sub
or m_cipher.replace. These lines are executed no matter what, so code
coverage is not suitable.
I have gone through each step in the translate functions and made sure
there is at least one ciphersuite per step

Having a list of every ciphersuite suggests that it should be maintained with
any new ciphersuites that are added in the future. This in turn almost defeats
the purpose of having translation functions to begin with
Instead, the unit test now only test a much smaller subset of ciphersuite names
that exercise each stage in the OpenSSL and GnuTLS translate functions.
In the future, if a new cipersuite is added that requires an extra stage in
translation, then that cipher can be added to the test suite, otherwise it
should not be necessary.

As test_translate_ciphers_format.sh was made as a testing ground before
utilising translate_ciphers.py in compat.sh, once it was translated to
python code - as a unit test, it became redundant.

Rather than having the tests seperated into different files, they were integrated
into translate_ciphers.py and can be run from root using:
`python -m unittest tests/scripts/translate_ciphers.py`
test_translate_ciphers_format.sh was originally made as a testing ground before
having the translation tool being implmented into compat.sh. Translating it to
python code makes it redundant and therefore it will be removed.

test_translate_ciphers_names.py
- Combined m, o and g ciphers all into one a single list of tuples to
avoid needing to rely on indexes
test_translate_ciphers_format.sh
- Removed redundant test
- Added return errors
compat.sh
- Improved how translate_ciphers.py is called
translate_ciphers.py
- Improve regex and translation to be more intutive and efficient
- change how arguments are taken and handelled to be more reliable

As per check-python-files.sh, added string documentation for
files and functions.
Modified for loops to use enumerate rather than range(len(
although as the same iteration index is used for multiple
lists it does not seem quite appropriate
