What I did

Added so all rules concerning dnf (DL3038, DL3040, DL3041) works analogously for microdnf as well, which closes #742. Note that I have not updated any documentation for the corresponding rule changes, since I wasn't sure if and how this should be done.

How I did it

Added utility function cmdsHaveArgs :: [Text.Text] -> [Text.Text] -> Command -> Bool in Shell.hs, which is a generalized version of the function cmdHasArgs. The function has been used to check for the rules concerned in this PR.

How to verify it

Test cases have been added so running the tests should be good enough. One can also run hadolint with the following file:

FROM centos:1.0    
    
RUN microdnf install test-1.0.0 && microdnf clean all # Missing -y flag    
RUN microdnf install -y test-1.0.0 # Missing microdnf clean all    
RUN microdnf install -y test && microdnf clean all # Missing version of package test    
RUN microdnf -y install test-1.0.0 && microdnf clean all # Passes all rules 

which outputs:

Dockerfile:3 DL3038 warning: Use the -y switch to avoid manual input `dnf install -y <package`
Dockerfile:4 DL3040 warning: `dnf clean all` missing after dnf command.
Dockerfile:5 DL3041 warning: Specify version with `dnf install -y <package>-<version>`.

Note that all warnings says dnf and not microdnf.
