Allow hyphens in custom command names and aliases

[paduszyk]

Description

Custom command names and aliases, defined via MANAGEMENT_COMMANDS_PATHS and MANAGEMENT_COMMANDS_ALIASES dictionaries, settings don't necessarily have to be Python identifiers as they don't refer to Python modules. Including hyphens imitating spaces would allow the creation of more human-readable names and aliases.

For example, instead of fullcheck, one could define full-check.

Suggested Solution

Command names/aliases are validated using a helper function:

django-management-commands/src/management_commands/conf.py

Lines 10 to 11 in 1558c0f

	def _is_identifier(s: str) -> bool:
	return s.isidentifier() and not iskeyword(s)

It can be extended to return True for strings containing hyphens.
