Remove hard dependency on other services

Closes #9

See merge request gaia-x/data-infrastructure-federation-services/tsa/policy!13

the clients will return an error which will be logged
and an error message will be returned to the caller.
This allows the policy service to continue working with
policies which doesn't require the use of additional
TSA services like cache, task, signer and did resolver.
