NOTE: This class is only intended for internal use.
This class handles the creation and ordering of the various credential
providers that primarly source their configuration from the shared config.
This is needed to enable sharing between the default credential chain and
the source profile chain created by the assume role provider.

The ``access_key``, ``secret_key``, and ``token`` properties
on this class will always check and refresh credentials if
needed before returning the particular credentials.
This has an edge case where you can get inconsistent
credentials. Imagine this:
# Current creds are "t1"
tmp.access_key ---> expired? no, so return t1.access_key
# ---- time is now expired, creds need refreshing to "t2" ----
tmp.secret_key ---> expired? yes, refresh and return t2.secret_key
This means we're using the access key from t1 with the secret key
from t2. To fix this issue, you can request a frozen credential object
which is guaranteed not to change.
The frozen credentials returned from this method should be used
immediately and then discarded. The typical usage pattern would
be::
creds = RefreshableCredentials(...)
some_code = SomeSignerObject()
# I'm about to sign the request.
# The frozen credentials are only used for the
# duration of generate_presigned_url and will be
# immediately thrown away.
request = some_code.sign_some_request(
with_credentials=creds.get_frozen_credentials())
print("Signed request:", request)

zCredentialProvider.__init__c C s dS )a~
Loads the credentials from their source & sets them on the object.
Subclasses should implement this method (by reading from disk, the
environment, the network or wherever), returning ``True`` if they were
found & loaded.
If not found, this method should return ``False``, indictating that the
``CredentialResolver`` should fall back to the next available method.
The default implementation does nothing, assuming the user has set the
``access_key/secret_key/token`` themselves.
:returns: Whether credentials were found & set
:rtype: Credentials
