Return the shell command to run to create the erasure code profile
described by the profile parameter.

:param profile: a map whose semantic depends on the erasure code plugin
:returns: a shell command as an array suitable for Remote.run
If profile is {}, it is replaced with
{ 'k': '2', 'm': '1', 'ruleset-failure-domain': 'osd'}
for backward compatibility. In previous versions of teuthology,
these values were hardcoded as function arguments and some yaml
files were designed with these implicit values. The teuthology
code should not know anything about the erasure code profile
content or semantic. The valid values and parameters are outside
its scope.
