Let generic AVPs be encoded/decoded in alternate dictionaries
To support specifications like RFC 7683 DOIC, that only define AVPs, not applications. AVPs that aren't known to the application dictionary in question could previously not be decoded. Configuring alternate dictionaries with the new transport/service option avp_dictionaries changes this, so that AVPs like DOIC's Grouped OC-OLR can presented in their fully decoded glory. Encode is also extended, allowing things like the following to be encoded in an outgoing message: 'AVP' => [{'OC-OLR', #{'OC-Sequence-Number' => 1, 'OC-Report-Type' => 0, 'OC-Reduction-Percentage' => [25]}}] A diameter_gen_doic_rfc7683 dictionary is installed, but avp_dictionaries isn't specific to DOIC. This commit also solves the problem demonstrated a few commits back, that application AVPs aren't decoded in answers setting the E-bit. Test coverage will come in a subsequent commit.
