Feature Request: extend default config

[haysclark]

It would be nice to have a smaller config file when only making small alterations to the Default Config of commitlint. Adding a behavior allowing users to override the default config would allow for much smaller .commitlint.yaml files.

e.g.

# .commitlint.yaml

extends: default
# or maybe
formatter: overwrite # or `extend`, 'overlay', 'merge', ...etc

# then just what values should be overwritten
settings:
  # Loosen up on the line lengths
  header-max-length:
    argument: 72
  body-max-line-length:
    argument: 100
  footer-max-line-length:
    argument: 100

Hi @haysclark

sorry for the late reply

i like the idea of extending/overriding from a base config like default.
will explore the idea.
also, just released v0.11.0, which loosens the max line length by default (72, 100, 100)
