Should have a way to print all supported modes and available params

[MrHohn]

There is currently no way to know what modes are supported, what parameters are available for each mode and how to use them, unless you read the READMEs in this repo.

We should be able to print these out via the binary as well. Probably through:

$ cluster-proportional-autoscaler --show-modes
# Show available modes, each has one line description.
$ cluster-proportional-autoscaler --show-usage $MODE_NAME
# Show available params and usage.

How would this work, someone would docker run the container with a different entrypoint with the help flags? It is true that it would be good to build the help into the package, but the mechanism to access the help text seems a little obscure.

@bowei i am planning to include argument option in command which will display corresponding text file content
for example:
cluster-proportional-autoscaler --show-modes
this will invoke content of text file containing all modes and its information.
