uac: allow ha1 to be used in uac_reg_request_to

[covalschi]

Description

I'm using uac module to remote authenticate to a trunk. With the addition of ha1 used instead of plaintext password it is also would be nice to be able to use uac_reg_request_to with it.

Expected behavior

There should be auth_ha1_avp for uac module, which will use ha1 instead of plaintext to build the request

Actual observed behavior

auth_password_avp is set to empty string or dot respectively of how you specify it in database, ha1 is not used in uac_reg_request_to

Possible Solutions

Well logically auth_ha1_avp should be prioritized over auth_password_avp

Feature added in master using mode parameters for uac_reg_request_to() and uac_auth() -- see the readme of the module. In this way, the uac_auth() has support for ha1 passwords even when using the credentials modparam.

I haven't tested, therefore feedback with the results of testing are appreciated.
