Add new constants to password service. Change infinite expiration time.

[Issue#]        SSDWSSP-700
[Feature/Bug]   Add PASSWORD_INFINITE_EXPIRATION_TIME and PASSWORD_INFINITE_ATTEMPT_COUNT constant
                to password service. Change infinite expiration time.
[Cause]         Infinite expiration time and infinite attempt count were inputed directly to
                variables in multiple places. Other infinite expiration time
[Solution]      Constants were added for simplier switching between different infinite expiration
                times and infinite attempt  counts.
[Verification]  Build, install, run tests. All should pass, except tests that treated infinite
                expiration time as 0 value.
