Flex model fields as time series

[Flix6x]

This serves as a page to track compatibility of passing time series within API and CLI flex model fields. That is, which fields already support passing a time series directly, instead of pointing to a sensor:

Field in flex model	API support since	CLI support since	References
soc-at-start
soc-unit	-	-	not relevant
soc-min
soc-max
soc-minima	v0.14		#680
soc-maxima	v0.14		#680
soc-targets	v0.9	v0.9	#396, #372
soc-gain	v0.23 (planned)		#1127
soc-usage	v0.23 (planned)		#1127
roundtrip-efficiency	-	-	not planned
charging-efficiency	v0.23 (planned)		#1127
discharging-efficiency	v0.23 (planned)		#1127
storage-efficiency	v0.23 (planned)		#1127
prefer-charging-sooner	-	-	not planned
power-capacity	v0.23 (planned)		#1127
consumption-capacity	v0.23 (planned)		#1127
production-capacity	v0.23 (planned)		#1127

Similarly, for flex context fields:

Field in flex context	API support since	CLI support since	References
consumption-price-sensor	-	-	not planned
production-price-sensor	-	-	not planned
inflexible-device-sensors	-	-	not planned
site-power-capacity	v0.23 (planned)		#1127
site-production-capacity	v0.23 (planned)		#1127
site-consumption-capacity	v0.23 (planned)		#1127
