Add ~/.bmx/credentials support to `write` about bmx HOT 3 CLOSED

Support for ~/.bmx/credentials means a couple of things:

1. write will look for cached credentials in ~/.bmx/credentials before getting a new STS token.
2. Once it gets credentials, write writes them to ~/.aws/credentials (as you said, this is the primary case).
3. If everything is successful, write caches the AWS creds into ~/.bmx/credentials. Every BMX command should follow this pattern: the last used AWS credentials should be the default in ~/.bmx/credentials.

Does that answer your question, @mtjandra ?

Why would you ever want to write into ~/.bmx/credentials? I actually thought we wanted to write to ~/.aws/credentials in the case you want to get some keys before running some other script that uses boto3 or awscli. If using bmx just use bmx commands?

Yup thanks for the clarification @chris-redekop I thought we were removing feature you mentioned in point #2.
