Fixes #288 - adds abbreviated argument flags for power users

[kmcquade]

What does this PR do?

Adds abbreviated argument flags, which fixes #288. I had several users request this feature because it would take too long to write the commands.

Here are the new argument options:

policy_sentry write-policy

• --input-file: -i
• --mimimize: -m

policy_sentry create-template

• --output-file: -o
• --template-type: -t

For the query functions:

• --service: -s
• --name: -n
• --access-level: -a
• --condition: -c
• --resource-type: -r
• --list-arn-types: -l

Note: I opted to not set an abbreviated argument flag for --fmt because the -f flag is usually used for "file". To avoid confusion, I just left it as --fmt
