Update units of measurement in Create modal

[jgiardino]

In the Create modal, we currently display values using decimal/metric units instead of binary when representing bytes. We should update our units of measure to use binary units following the PF guidelines.

Specifically, these updates are needed:

label	current text	proposed text
Ingress/Egress	up to 2 MB/second each	up to 2 MiB/second each
		Note that PF guidelines recommend MiBps for rate, but we have another value represented as "connections/second" and therefore use "/second" here for consistency
Storage	up to 60 GB	up to 60 GiB
Message size	up to 1 MB	up to 1 MiB

In a discussion related to metrics and the units of measure that we use, the following feedback was provided:

• the Ingress/Egress is actually set to 2MiB/second
• for Storage, we could change advertise as 60GiB, since it's actually somewhere between 80-90GiB in reality
• the max.message.bytes is at the default of 1048588, which is 1MiB, so that one could also be changed

Note that Topic properties currently use binary units as well.
