Describe the issue:

1. The following four tables contain the wrong type "Resources" (same issues).
We think all of them should be not "Resources" but "Requests".

+ "Table 1.6. Proxy parameters" in "1.12.3.1. Istio global example"[1]
+ "Table 1.9. Istio Mixer telemetry parameters" in "1.12.3.3. Istio Mixer configuration"[1]

+ "Table 2.3. Proxy parameters" in "2.11.3.1. Istio global example"[2]
+ "Table 2.6. Istio Mixer telemetry parameters" in "2.11.3.3. Istio Mixer configuration"[2]

2. "Table 1.6. Proxy parameters" in "1.12.3.1. Istio global example"[1] shows the default
values of "resources.requests" and "resources.limits" as follow:

------------------------------------------------------------
Resources (Note: This should be changed to "Requests" as indicated in #1 above)

• cpu: 10m
• memory: 1024Mi
  ^^^^^^^^^^^^^^ (A)
  Limits:
• cpu: 2000m
• memory: 128Mi
  ^^^^^^^^^^^^^ (B)
  ------------------------------------------------------------

The "Requests" memory 1024Mi (A) seems to be invalid because it can not exceed the "Limits" memory 128Mi (B).

Note1: The "Requests" memory 1024Mi seems to have been changed by PR#20952[3][4].

Note2: Our partner mentions that here are the default values of sidecar resource on OCP4.6.
