columnstoreAlias script breaks on x-api-key containing '=' characters

mcsapikey=$(grep -r 'x-api-key' /etc/columnstore/cmapi_server.conf | cut -d= -f2 | xargs)

The cut -d= is meant to seperate the key/value to store as variable in script
This line does not handle if the x-api-key value contains an actual '=' characters and will break the commands giving 401 errors.

Command should be modified to the following

mcsapikey=$(grep -r 'x-api-key' /etc/columnstore/cmapi_server.conf | cut -d= -f2- | xargs)
