While we get packaging sorted, Net::OAuth2::AuthorizationServer is not a
hard dependency for Koha and the feature requiring it is disabled by
default.
This patch:
- Makes the dependency optional
- Makes the unit tests for the OAuth2 client credentials flow skip if
the dependency is not met.

This patch makes the /token endpoint and the authenticate_api_request
method behave correctly in the event of missing deps for OAuth2.
To test:
- Run:
$ kshell
k$ prove t/db_dependent/api/v1/oauth.t
=> FAIL: The behaviour is not implemented
- Apply this patch
- Run:
k$ prove t/db_dependent/api/v1/oauth.t
=> SUCCESS: Tests pass!

This patch makes the /api/v1/oauth/token enpoint respect the
RESTOAuth2ClientCredentials syspref. It will return 400 (with
'Unimplemented grant type' error message) on the event of the syspref
being disabled and the grant_type => 'client_credentials' value passed.
To test:
- Run:
$ kshell
k$ prove t/db_dependent/api/v1/oauth.t
=> FAIL: It fails because the off-switch is not implemented
- Apply this patch
- Run:
k$ prove t/db_dependent/api/v1/oauth.t
=> SUCCESS: Tests pass!
- Sign off :-D

It implements only the "client credentials" flow with no scopes
support. API clients are tied to an existing patron and have the same
permissions as the patron they are tied to.
API Clients are defined in $KOHA_CONF.
Test plan:
0. Install Net::OAuth2::AuthorizationServer 0.16
1. In $KOHA_CONF, add an <api_client> element under <config>:
<api_client>
<client_id>$CLIENT_ID</client_id>
<client_secret>$CLIENT_SECRET</client_secret>
<patron_id>X</patron_id> <!-- X is an existing borrowernumber -->
</api_client>
2. Apply patch, run updatedatabase.pl and reload starman
3. Install Firefox extension RESTer [1]
4. In RESTer, go to "Authorization" tab and create a new OAuth2
configuration:
- OAuth flow: Client credentials
- Access Token Request Method: POST
- Access Token Request Endpoint: http://$KOHA_URL/api/v1/oauth/token
- Access Token Request Client Authentication: Credentials in request
body
- Client ID: $CLIENT_ID
- Client Secret: $CLIENT_SECRET
5. Click on the newly created configuration to generate a new token
(which will be valid only for an hour)
6. In RESTer, set HTTP method to GET and url to
http://$KOHA_URL/api/v1/patrons then click on SEND
If patron X has permission 'borrowers', it should return 200 OK
with the list of patrons
Otherwise it should return 403 with the list of required permissions
(Please test both cases)
7. Wait an hour (or run the following SQL query:
UPDATE oauth_access_tokens SET expires = 0) and repeat step 6.
You should have a 403 Forbidden status, and the token must have been
removed from the database.
8. Create a bunch of tokens using RESTer, make some of them expires
using the previous SQL query, and run the following command:
misc/cronjobs/cleanup_database.pl --oauth-tokens
Verify that expired tokens were removed, and that the others are
still there
9. prove t/db_dependent/api/v1/oauth.t
