Context manager for AWS Profiles
Authorize your shell by some ways with specified profile name.
Then, you get ~/.aws/credentials like
```
[foo]
awsaccesskeyid = XXXXXXXXXXX
awssecretaccesskey = XXXXXXXXXXX
awssessiontoken = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
[bar] awsaccesskeyid = YYYYYYYYYYY awssecretaccesskey = YYYYYYYYYYY awssessiontoken = YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY ```
list-contexts shows all the named profiles as the below.
console
$ ctxm list-contexts
foo
bar
use-context update ~/.aws/credentials to contain default profile that the values are same as specified in the option.
console
$ ctxm use-context -p foo
e.g. the above commands updates credentials as the below.
```
[foo]
awsaccesskeyid = XXXXXXXXXXX
awssecretaccesskey = XXXXXXXXXXX
awssessiontoken = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
[bar] awsaccesskeyid = YYYYYYYYYYY awssecretaccesskey = YYYYYYYYYYY awssessiontoken = YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
[default] awsaccesskeyid = XXXXXXXXXXX awssecretaccesskey = XXXXXXXXXXX awssessiontoken = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX ```
