Code completion for standard resources keys (mem_mb, etc.) + resource_scopes

[iromeo]

See examples in https://snakemake.readthedocs.io/en/stable/snakefiles/rules.html#standard-resources

• mem, mem_mb, mem_mib, ...
• disk, disk_mb, disk_mib, ...
• tmp_dir
• runtime

See datails in https://snakemake.readthedocs.io/en/stable/snakefiles/rules.html#resources

Example for resource scopes:

resource_scopes:
    fake_res="local",
    mem_mb="global",

rule a:
    resources:
        mem_mb=20000,
        fake_res=400,
        global_res=1000,
        runtime=80,
        ```
        (see https://snakemake.readthedocs.io/en/stable/snakefiles/rules.html#resources-and-remote-execution)
