ZCS-16412: Added command to manage the proxy timeout

[swathy-shaji]

Ticket - ZCS-16412

To make the proxy time-out configurable
We are providing the privilege to the user to manage this value through zmlicensectl --service command

To get the proxy timeout - zmlicensectl --service getProxyTimeout
To set the proxy timeout - zmlicensectl --service setProxyTimeout=60

Please note : We are setting the value to 3 properties internally, timeout, socketTimeout, readTimeout

Output

zimbra@telus-dev-1:~$ zmlicensectl --service setProxyTimeout=20
Error: Proxy timeout must be greater than 60.
zimbra@telus-dev-1:~$ zmlicensectl --service setProxyTimeout=
Error: Proxy timeout value is missing.
zimbra@telus-dev-1:~$ zmlicensectl --service setProxyTimeout=70
zimbra@telus-dev-1:~$ zmlicensectl --service getProxyTimeout
Current proxy timeout: 70 seconds
