A refresh is needed if the expiry time associated
with the temporary credentials is less than the
provided ``refresh_in``. If ``time_delta`` is not
provided, ``self.advisory_refresh_needed`` will be used.
For example, if your temporary credentials expire
in 10 minutes and the provided ``refresh_in`` is
``15 * 60``, then this function will return ``True``.
:type refresh_in: int
:param refresh_in: The number of seconds before the
credentials expire in which refresh attempts should
be made.

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)

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.
