Add minimum/maximum to counter

[rohankapoorcom]

Description:

@spacemanspiff2007 originally submitted #17440 and #20319 to add a minimum/maximum to the counter component. Unfortunately, these PRs were never able to be driven to completion. I'd like to resubmit their work and take care of driving it to completion as this is functionality that I believe that the counter needs to support.

Pull request in home-assistant.io with documentation (if applicable): home-assistant/home-assistant.io#9086

Example entry for configuration.yaml (if applicable):

counter:
  my_counter:
    initial: 0
    step : 1
    minimum: 0
    maximum: 10

Checklist:

• The code change is tested and works locally.
• Local tests pass with tox. Your PR cannot be merged unless tests pass
• There is no commented out code in this PR.

If user exposed functionality or configuration variables are added/changed:

• Documentation added/updated in home-assistant.io

If the code communicates with devices, web services, or third-party tools:

• New dependencies have been added to the REQUIREMENTS variable (example).
• New dependencies are only imported inside functions that use them (example).
• New or updated dependencies have been added to requirements_all.txt by running script/gen_requirements_all.py.
• New files were added to .coveragerc.

If the code does not interact with devices:

• Tests have been added to verify that the new code works.
