Improved KAS key management tools

[dmihalcik-virtru]

We currently don't support KAS key management very well

1. Introduce service keys subcommand to otdfctl:
   a. init: similar to current init-temp-keys script, this creates new keys
   b. create: Adds new key or keys of requested type
   c. import: Adds existing keys of the requested type
2. These keys update the opentdf.yaml file with the new key information.

Things to think about:

• the keys should be stored in jwk sets
• all keys must be compatible with existing clients
• should be an opentdf subcommand set, to simplify deployment
• must work on windows

Subtasks:

• JWKS for KAS keys #1085
• init-key script should error out if keys with the same names already exist #894
• Keys Init Script Fails #778
• platform: Let people easily configure KAS keys with a command line tool #769
• Unable to run the platform scripts in a Windows environment #616
