v0.12.2 - TEDAPI Cache Expiration Fix

v0.12.2 - Cache Expiration Fix

• Fix bug in cache expiration timeout code that was not honoring pwcacheexpire setting. Raised by @erikgieseler in Is PW_CACHE_EXPIRE=0 not possible? (Proxy) #122 - PW_CACHE_EXPIRE=0 not possible? (Proxy)
• Add WARNING log in proxy for settings below 5s.
• Change TEDAPI config default timeout from 300s to 5s and link to pwcacheexpire setting.

Closes #122

The cache time for config was set to 300s (5m) - I think the basis was to reduce load on TEDAPI for mostly static (config) data, but this impacts the "battery reserve setting" data as well. I can't recall if this was to address any reported issue where the config data timeout helped address stability.

For consistency, I'm updating the 300s to match the status data timeout of 5s. It will also match the explicit cache time setting if provided in the Powerwall object constructor.

I will run this a while in full mode to ensure no negative impact.
