Subject: [PATCH 79/83] CACHE_REQ: Add plugin methods required for the

 domain-locator request

MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit

Adds three new cache_req plugin methods:

    - cache_req_dp_get_domain_check_fn - check if it is time to run the

                                         locator request again

    - cache_req_dp_get_domain_send/recv_fn - run the locator itself

The reason we added also the checker is that when the locator runs,

we add a temporary entry into the negative cache that would denote that

the locator ran and the ordinary domain negative cache (UID negcache,

GID negcache, ..) were set for the domains and can be still used to

skip domains that we know do not contain the account without calling

the getAccountDomain handler again.

If we didn't have this checker, requesting an entry from a domain

further down the domain list would always call the locator, only

to always receive the same results.
