Add hist_all_htapes namelist flag to output all history fields

[johnpaulalex]

Also made rah1 history field properly initialize itself (it was not overwriting its NaNs to spvals like every other field does)

Specific notes

Contributors other than yourself, if any: @ekluzek, @samsrabin

CTSM Issues Fixed (include github issue #):

• Resolves add namelist option to turn on all history fields, add a CLM test that uses this #29

Are answers expected to change (and if so in what way)? No

Any User Interface Changes (namelist or namelist defaults changes)? Added new hist_all_htapes namelist flag, defaults to false (a no-op).

Testing performed, if any:

• SMS_D_Ld3.f10_f10_mg37.I1850Clm50BgcCrop.derecho_gnu.clm-default--clm-all_outputs gets 1369 variables saved to the h0 file.
• ERP_Ld9.f45_f45_mg37.I2000Clm50FatesRs.derecho_intel.clm-FatesColdAllVars now has two extra variables.

Looks like this does affect FATES variables too; after e53049f, the FatesColdAllVars test has two more variables. That's not as many as I expected based on #2833, but that might be due to FATES mode settings.

I ran testing. Izumi was fine.
A few unexpected fails pm Derecho to look into, mostly build errors....
