Reproduction steps

Create VM agent template and use usageMode. Set it to EXCLUSIVE or "EXCLUSIVE"
Initial configruation is loaded but the UI still shows localized message for NORMAL mode.
when trying to change the usageMode option from UI and save template Jenkins error occurs.

The exception is

java.lang.IllegalArgumentException: No enum constant hudson.model.Node.Mode.Wykorzystuj ten węzeł tak bardzo, jak to tylko możliwe
    at java.lang.Enum.valueOf(Enum.java:238)
    at org.kohsuke.stapler.RequestImpl$TypePair.convertJSON(RequestImpl.java:745)

Caused: java.lang.IllegalArgumentException: Failed to convert the usageMode parameter of the constructor public com.microsoft.azure.vmagent.AzureVMAgentTemplate(java.lang.String,java.lang.String,java.lang.String,java.lang.String,com.microsoft.azure.vmagent.AzureVMAgentTemplate$AvailabilityTypeClass,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,hudson.model.Node$Mode,java.lang.String,java.lang.String,com.microsoft.azure.vmagent.AzureVMAgentTemplate$ImageReferenceTypeClass,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.lang.String,hudson.slaves.RetentionStrategy,boolean,boolean)

    at org.kohsuke.stapler.RequestImpl.access$200(RequestImpl.java:85)
    at org.kohsuke.stapler.RequestImpl$TypePair.convertJSON(RequestImpl.java:690)

So as we can see when trying to set this option from UI it takes the localized description and tries to convert it to Enum and it fails.

Results

Expected result:

I can usccessfuly change the usageMode option from UI and also when loading yml file the correct option is selected from the dropdown.

Actual result:

Exception is thrown and configuration fails.
