New lastpass export type for AWS IAM credentials

[austinweisgrau]

IAM credentials can now be exported with keys AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY instead of username and password, which allows for a more seamless AWS credentialing flow with db-facts

[austinweisgrau]

Going to add these notes to a readme:

Needs to be added to the config (expected at /usr/local/etc/dbfacts.yml)

Under exports_from:

  lpass_aws_iam:
    pull_lastpass_aws_iam: "{{ lastpass_entry }}"

Then create new entries under dbs (or modify existing ones) using the lpass_aws_iam exports_from type. Example:

  aws_influencers_pipeline:
    exports_from: lpass_aws_iam
    lastpass_entry: 'AWS IAM (adhoc): influencers.pipeline'

Then you can run eval $(db-facts sh aws_influencers_pipeline) to credential your shell with AWS credentials from that lastpass entry.

Good for a quick merge,

MITCH-TODO (Flagging for future look), Need to investigate in operator using a elif fallthrough tree for OoO concerns.
