Auto completion for PROJECT_MODULES

[Greewil]

It would be much easier to type vuh commands for monorepos with auto completion for PROJECT_MODULES.
F.e. if there monorepo has next project modules:

PROJECT_MODULES='BACKEND, FRONTEND'

completion should help you with typing commands:

# If you typing:
vuh uv -pm=BA[tab]
# it should complete word
vuh uv -pm=BACKEND

# If you typing:
vuh uv -pm=[tab][tab]
# it should show both variants
vuh uv -pm=
BACKEND     FRONTEND
