Is your feature request related to a problem? Please describe.
Unable to set environment setting that contains an equal sign. F

Describe the solution you'd like
We should be able to escape the equal sign in the value of an environment setting either with a slash ('') or by wrapping the entire value in quotes

az batch task create --environment-setting ConnectionString="Server=tcp:servername,1433"

or

az batch task create --environment-setting ConnectionString=Server\=tcp:servername,1433

Describe alternatives you've considered

Additional context
If I attempt to set a connection string like such SqlConnection="Server=tcp:servername.database.windows.net,1433;Initial Catalog=sqldb-app-dev_simplesearch;Persist Security Info=False;MultipleActiveResultSets=False;Encrypt" this fails with error invalid environment_setting_format
